Louis Armstrong

Armstrong was a member of Fate Marable's New Orleans Band in 1918, here on board the S.S. Sidney

Early in his career, Armstrong played in brass bands and riverboats in New Orleans, first on an excursion boat in September 1918. He traveled with the band of Fate Marable, which toured on the steamboat Sidney with the Streckfus Steamers line up and down the Mississippi River.[36] Marable was proud of his musical knowledge, and he insisted that Armstrong and other musicians in his band learn sight reading. Armstrong described his time with Marable as "going to the University", since it gave him a wider experience working with written arrangements. In 1919, Armstrong's mentor, King Oliver decided to go north and resigned his position in Kid Ory's band; Armstrong replaced him. He also became second trumpet for the Tuxedo Brass Band.[37]

Throughout his riverboat experience, Armstrong's musicianship began to mature and expand. At twenty, he could read music. He became one of the first jazz musicians to be featured on extended trumpet solos, injecting his own personality and style. He also started singing in his performances.[38]

In 1922, Armstrong moved to Chicago at the invitation of King Oliver,[39] although Armstrong would return to New Orleans periodically for the rest of his life.[40] Playing second cornet to Oliver in Oliver's Creole Jazz Band in the black-only Lincoln Gardens in Chicago's black neighborhood, he could make enough money to quit his day jobs. Although race relations were poor, Chicago was booming. The city had jobs for blacks making good wages at factories with some left over for entertainment.[39]^: 86

Oliver's band was among the most influential jazz bands in Chicago in the early 1920s. Armstrong lived luxuriously in his own apartment with his first private bath. Excited as he was to be in Chicago, he began his career-long pastime of writing letters to friends in New Orleans. Armstrong could blow two hundred high Cs in a row. As his reputation grew, he was challenged to cutting contests by other musicians.[41]

His first studio recordings were with Oliver for Gennett Records on April 5–6, 1923. They endured several hours on the train to remote Richmond, Indiana, and the band was paid little. The quality of the performances was affected by lack of rehearsal, crude recording equipment, bad acoustics, and a cramped studio. These early recordings were true acoustic, the band playing directly into a large funnel connected directly to the needle making the groove in the master recording. (Electrical recording was not invented until 1926 and Gennett installed it later.) Because Armstrong's playing was so loud, when he played next to Oliver, Oliver couldn't be heard on the recording. Armstrong had to stand fifteen feet away from Oliver, in a far corner of the room.[42]

Lil Hardin, who Armstrong would marry in 1924, urged Armstrong to seek more prominent billing and develop his style apart from the influence of Oliver. At her suggestion, Armstrong began to play classical music in church concerts to broaden his skills; and he began to dress more in more stylish attire to offset his girth. Her influence eventually undermined Armstrong's relationship with his mentor, especially concerning his salary and additional money that Oliver held back from Armstrong and other band members.[43] Armstrong's mother, May Ann Albert, came to visit him in Chicago during the summer of 1923 after being told that Armstrong was "out of work, out of money, hungry, and sick"; Hardin located and decorated an apartment for her to live in while she stayed.[44]

Armstrong and Oliver parted amicably in 1924. Shortly afterward, Armstrong received an invitation to go to New York City to play with the Fletcher Henderson Orchestra, the top African-American band of the time. He switched to the trumpet to blend in better with the other musicians in his section. His influence on Henderson's tenor sax soloist, Coleman Hawkins, can be judged by listening to the records made by the band during this period.[45][46]

Armstrong adapted to the tightly controlled style of Henderson, playing trumpet and experimenting with the trombone. The other members were affected by Armstrong's emotional style. His act included singing and telling tales of New Orleans characters, especially preachers.[47] The Henderson Orchestra played in prominent venues for white patrons only, including the Roseland Ballroom, with arrangements by Don Redman. Duke Ellington's orchestra went to Roseland to catch Armstrong's performances.

During this time, Armstrong recorded with Clarence Williams (a friend from New Orleans), the Williams Blue Five, Sidney Bechet, and blues singers Alberta Hunter, Ma Rainey, and Bessie Smith.[48][49]

In 1925, Armstrong returned to Chicago largely at the insistence of Lil, who wanted to expand his career and his income. In publicity, much to his chagrin, she billed him as "the World's Greatest Trumpet Player". For a time he was a member of the Lil Hardin Armstrong Band and working for his wife.[50] He formed Louis Armstrong and his Hot Five and recorded the hits "Potato Head Blues" and "Muggles". The word "muggles" was a slang term for marijuana, something he used often during his life.[39]

"Heebie Jeebies" by Louis Armstrong and his Hot Five

The Hot Five included Kid Ory (trombone), Johnny Dodds (clarinet), Johnny St. Cyr (banjo), Lil Armstrong on piano, and usually no drummer. Over a twelve-month period starting in November 1925, this quintet produced twenty-four records.[51] Armstrong's band leading style was easygoing, as St. Cyr noted, "One felt so relaxed working with him, and he was very broad-minded ... always did his best to feature each individual."[52] Among the most notable of the Hot Five and Seven records were "Cornet Chop Suey", "Struttin' With Some Barbecue", "Hotter Than that" and "Potato Head Blues", all featuring highly creative solos by Armstrong. According to Thomas Brothers, recordings, such as "Struttin' with Some Barbeque", were so superb, "planned with density and variety, bluesyness, and showiness," that the arrangements were probably showcased at the Sunset Café.[53] His recordings soon after with pianist Earl "Fatha" Hines, most famously their 1928 "Weather Bird" duet and Armstrong's trumpet introduction to and solo in "West End Blues", remain some of the most famous and influential improvisations in jazz history. Young trumpet players across the country bought these recordings and memorized his solos.

Armstrong was now free to develop his personal style as he wished, which included a heavy dose of effervescent jive, such as "Whip That Thing, Miss Lil" and "Mr. Johnny Dodds, Aw, Do That Clarinet, Boy!"[54]

Armstrong also played with Erskine Tate's Little Symphony, which played mostly at the Vendome Theatre. They furnished music for silent movies and live shows, including jazz versions of classical music, such as "Madame Butterfly", which gave Armstrong experience with longer forms of music and with hosting before a large audience. He began to scat sing (improvise vocal jazz using nonsensical words) and was among the first to record it, on the Hot Five recording "Heebie Jeebies" in 1926. The recording was so popular that the group became the most famous jazz band in the United States, even though they had not performed live to any great extent. Young musicians across the country, black or white, were turned on by Armstrong's new type of jazz.[55]

After separating from Lil, Armstrong started to play at the Sunset Café for Al Capone's associate Joe Glaser in the Carroll Dickerson Orchestra, with Earl Hines on piano, which was renamed Louis Armstrong and his Stompers,[56] though Hines was the music director and Glaser managed the orchestra. Hines and Armstrong became fast friends and successful collaborators. It was at the Sunset Café that Armstrong accompanied singer Adelaide Hall. It was during Hall's tenure at the venue that she experimented, developed and expanded her use and art of scat singing with Armstrong's guidance and encouragement.[57]

In the first half of 1927, Armstrong assembled his Hot Seven group, which added drummer Al "Baby" Dodds and tuba player, Pete Briggs, while preserving most of his original Hot Five lineup. John Thomas replaced Kid Ory on trombone. Later that year he organized a series of new Hot Five sessions which resulted in nine more records. In the last half of 1928, he started recording with a new group: Zutty Singleton (drums), Earl Hines (piano), Jimmy Strong (clarinet), Fred Robinson (trombone), and Mancy Carr (banjo).[58]

Armstrong made a huge impact during the 1920s Harlem Renaissance within the Jazz world.[59] His music touched many, including a well-known writer during that time named Langston Hughes. Hughes admired Armstrong and acknowledged him as one of the most recognized musicians during the era.[60] Hughes created many books that upheld the central idea of jazz and gave recognition to Armstrong as one of the most important persons to be part of the Harlem Renaissance's newfound love of African-American culture.[61] The sound of jazz, along with many other musicians such as Armstrong, helped shape Hughes as a writer. Just like the musicians, Hughes wrote his words with jazz.[62]

Armstrong changed jazz during the Harlem Renaissance. Being known as "The World's Greatest Trumpet Player" during this time,[63] Armstrong continued his legacy and continued a focus on his own vocal career. The popularity he gained brought together many black and white audiences to watch him perform.[64]

Armstrong returned to New York in 1929, where he played in the pit orchestra for the musical Hot Chocolates, an all-black revue written by Andy Razaf and pianist Fats Waller. He also made a cameo appearance as a vocalist, regularly stealing the show with his rendition of "Ain't Misbehavin'". His version of the song became his biggest selling record to date.[65]

Armstrong started to work at Connie's Inn in Harlem, chief rival to the Cotton Club, a venue for elaborately staged floor shows,[66] and a front for gangster Dutch Schultz. Armstrong also had considerable success with vocal recordings, including versions of songs composed by his old friend Hoagy Carmichael. His 1930s recordings took full advantage of the new RCA ribbon microphone, introduced in 1931, which imparted a characteristic warmth to vocals and immediately became an intrinsic part of the 'crooning' sound of artists like Bing Crosby. Armstrong's interpretation of Carmichael's "Stardust" became one of the most successful versions of this song ever recorded, showcasing Armstrong's unique vocal sound and style and his innovative approach to singing songs that had already become standards.

Armstrong's radical re-working of Sidney Arodin and Carmichael's "Lazy River" (recorded in 1931) encapsulated many features of his groundbreaking approach to melody and phrasing. The song begins with a brief trumpet solo, then the main melody is introduced by sobbing horns, memorably punctuated by Armstrong's growling interjections at the end of each bar: "Yeah! ..."Uh-huh"..."Sure"..."Way down, way down." In the first verse, he ignores the notated melody entirely and sings as if playing a trumpet solo, pitching most of the first line on a single note and using strongly syncopated phrasing. In the second stanza he breaks into an almost fully improvised melody, which then evolves into a classic passage of Armstrong "scat singing".

As with his trumpet playing, Armstrong's vocal innovations served as a foundation stone for the art of jazz vocal interpretation. The uniquely gravelly coloration of his voice became a musical archetype that was much imitated and endlessly impersonated. His scat singing style was enriched by his matchless experience as a trumpet soloist. His resonant, velvety lower-register tone and bubbling cadences on sides such as "Lazy River" exerted a huge influence on younger white singers such as Bing Crosby.

The Great Depression of the early 1930s was especially hard on the jazz scene. The Cotton Club closed in 1936 after a long downward spiral and many musicians stopped playing altogether as club dates evaporated. Bix Beiderbecke died and Fletcher Henderson's band broke up. King Oliver made a few records but otherwise struggled. Sidney Bechet became a tailor, later moving to Paris and Kid Ory returned to New Orleans and raised chickens.[67]

Armstrong moved to Los Angeles in 1930 to seek new opportunities. He played at the New Cotton Club in Los Angeles with Lionel Hampton on drums. The band drew the Hollywood crowd, which could still afford a lavish night life, while radio broadcasts from the club connected with younger audiences at home. Bing Crosby and many other celebrities were regulars at the club. In 1931, Armstrong appeared in his first movie, Ex-Flame, and was also convicted of marijuana possession but received a suspended sentence.[68] He returned to Chicago in late 1931 and played in bands more in the Guy Lombardo vein and he recorded more standards. When the mob insisted that he get out of town,[69] Armstrong visited New Orleans, had a hero's welcome, and saw old friends. He sponsored a local baseball team known as Armstrong's Secret Nine and had a cigar named after him.[70] But soon he was on the road again. After a tour across the country shadowed by the mob, he fled to Europe.

After returning to the United States, he undertook several exhausting tours. His agent Johnny Collins's erratic behavior and his own spending ways left Armstrong short of cash. Breach of contract violations plagued him. He hired Joe Glaser as his new manager, a tough mob-connected wheeler-dealer, who began to straighten out his legal mess, mob troubles and debts. Armstrong also began to experience problems with his fingers and lips, aggravated by his unorthodox playing style. As a result, he branched out, developing his vocal style and making his first theatrical appearances. He appeared in movies again, including Crosby's 1936 hit Pennies from Heaven. In 1937, Armstrong substituted for Rudy Vallee on the CBS radio network and became the first African American to host a sponsored, national broadcast.[71]

Armstrong in 1953

After spending many years on the road, Armstrong settled permanently in Queens, New York in 1943, in contentment with his fourth wife, Lucille. Although subject to the vicissitudes of Tin Pan Alley and the gangster-ridden music business, as well as anti-black prejudice, he continued to develop his playing.

Bookings for big bands tapered off during the 1940s due to changes in public tastes. Ballrooms closed and there was competition from other types of music, especially pop vocals, becoming more popular than big band music. It became impossible under such circumstances to finance a 16-piece touring band.

A widespread revival of interest in the 1940s in the traditional jazz of the 1920s made it possible for Armstrong to consider a return to the small-group musical style of his youth. Armstrong was featured as a guest artist with Lionel Hampton's band at the famed second Cavalcade of Jazz concert held at Wrigley Field in Los Angeles, produced by Leon Hefflin Sr., on October 12, 1946.[72] He also led a highly successful small-group jazz concert at New York Town Hall on May 17, 1947, featuring Armstrong with trombonist/singer Jack Teagarden. During the concert, Armstrong and Teagarden performed a duet on Hoagy Carmichael's "Rockin' Chair" they then recorded for Okeh Records.

Armstrong's manager, Joe Glaser, dissolved the Armstrong big band on August 13, 1947, and established a six-piece traditional jazz group featuring Armstrong with (initially) Teagarden, Earl Hines and other top swing and Dixieland musicians, most of whom were previously leaders of big bands. The new group was announced at the opening of Billy Berg's Supper Club.

This group was called Louis Armstrong and His All Stars and included at various times Earl "Fatha" Hines, Barney Bigard, Edmond Hall, Jack Teagarden, Trummy Young, Arvell Shaw, Billy Kyle, Marty Napoleon, Big Sid "Buddy" Catlett, Cozy Cole, Tyree Glenn, Barrett Deems, Mort Herbert, Joe Darensbourg, Eddie Shu, Joe Muranyi and percussionist Danny Barcelona.

On February 28, 1948, Suzy Delair sang the French song "C'est si bon" at the Hotel Negresco during the first Nice Jazz Festival. Louis Armstrong was present and loved the song. On June 26, 1950, he recorded the American version of the song (English lyrics by Jerry Seelen) in New York City with Sy Oliver and his Orchestra. When it was released, the disc was a worldwide success and the song was then performed by the greatest international singers.

He was the first jazz musician to appear on the cover of Time magazine, on February 21, 1949. Louis Armstrong and his All Stars were featured at the ninth Cavalcade of Jazz concert also at Wrigley Field in Los Angeles produced by Leon Hefflin Sr. held on June 7, 1953, along with Shorty Rogers, Roy Brown, Don Tosti and His Mexican Jazzmen, Earl Bostic, and Nat "King" Cole.[73]

During the next 30 years, Armstrong played more than 300 performances a year. During this period, Armstrong made many recordings and appeared in over thirty films.

Armstrong in 1955

By the 1950s, Armstrong was a widely beloved American icon and cultural ambassador who commanded an international fanbase. However, a growing generation gap became apparent between him and the young jazz musicians who emerged in the postwar era such as Charlie Parker, Miles Davis, and Sonny Rollins. The postwar generation regarded their music as abstract art and considered Armstrong's vaudevillian style, half-musician and half-stage entertainer, outmoded and Uncle Tomism. "... he seemed a link to minstrelsy that we were ashamed of."[74] He called bebop "Chinese music".[75] While touring Australia in 1954, he was asked if he could play bebop. "'Bebop?' he husked. 'I just play music. Guys who invent terms like that are walking the streets with their instruments under their arms'".[76]

"Mack the Knife" was released in 1956.

In the 1960s, he toured Ghana and Nigeria.[77][78]

After finishing his contract with Decca Records, he became a freelance artist and recorded for other labels.[79][80] He continued an intense international touring schedule, but in 1959 he suffered a heart attack in Italy and had to rest.[81]

In 1964, after over two years without setting foot in a studio, he recorded his biggest-selling record, "Hello, Dolly!", a song by Jerry Herman, originally sung by Carol Channing. Armstrong's version remained on the Hot 100 for 22 weeks, longer than any other record produced that year, and went to No. 1 making him, at 62 years, 9 months and 5 days, the oldest person ever to accomplish that feat. In the process, he dislodged The Beatles from the No. 1 position they had occupied for 14 consecutive weeks with three different songs.[82]

Armstrong kept touring well into his 60s, even visiting part of the Communist Bloc in 1965. He also toured Africa, Europe, and Asia under the sponsorship of the US State Department with great success, earning the nickname "Ambassador Satch" and inspiring Dave Brubeck to compose his jazz musical The Real Ambassadors. By 1968, he was approaching 70 and his health began to give out. He suffered heart and kidney ailments that forced him to stop touring. He did not perform publicly at all in 1969 and spent most of the year recuperating at home. Meanwhile, his longtime manager Joe Glaser died. By the summer of 1970, his doctors pronounced him fit enough to resume live performances. He embarked on another world tour, but a heart attack forced him to take a break for two months.[84]

Armstrong made his last recorded trumpet performances on his 1968 album Disney Songs the Satchmo Way.[85]

The Louis Armstrong House Museum website states:

Judging from home recorded tapes now in our Museum Collections, Louis pronounced his own name as "Lewis". On his 1964 record "Hello, Dolly", he sings, "This is Lewis, Dolly" but in 1933 he made a record called "Laughin' Louie". Many broadcast announcers, fans, and acquaintances called him "Louie" and in a videotaped interview from 1983 Lucille Armstrong calls her late husband "Louie" as well. Musicians and close friends usually called him "Pops".[86]

In a memoir written for Robert Goffin between 1943 and 1944, Armstrong states, "All white folks call me Louie," perhaps suggesting that he himself did not, or that no whites addressed him by one of his nicknames such as Pops.[87] That said, Armstrong was registered as "Lewie" for the 1920 U.S. Census. On various live records he is called "Louie" on stage, such as on the 1952 "Can Anyone Explain?" from the live album In Scandinavia vol.1. The same applies to his 1952 studio recording of the song "Chloe", where the choir in the background sings "Louie ... Louie", with Armstrong responding "What was that? Somebody called my name?". "Lewie" is the French pronunciation of "Louis" and is commonly used in Louisiana.

Armstrong with Lucille Wilson (c. 1960s)

Armstrong was performing at the Brick House in Gretna, Louisiana, when he met Daisy Parker, a local prostitute. He started the affair as a client. He returned to Gretna on several occasions to visit her. He found the courage to look for her home to see her away from work. It was on this occasion he found out she had a common-law husband. Not long after this fiasco, Parker traveled to Armstrong's home on Perdido Street.[88] They checked into Kid Green's hotel that evening. On the next day, March 19, 1919, Armstrong and Parker married at City Hall.[88][89] They adopted a three-year-old boy, Clarence, whose mother, Armstrong's cousin Flora, had died soon after giving birth. Clarence Armstrong was mentally disabled as a result of a head injury at an early age, and Armstrong spent the rest of his life taking care of him.[90] His marriage to Parker ended when they separated in 1923.

On February 4, 1924, he married Lil Hardin Armstrong, King Oliver's pianist. She had divorced her first husband a few years earlier. His second wife helped him develop his career, but they separated in 1931 and divorced in 1938. Armstrong then married Alpha Smith.[91] His relationship with Alpha began while he was playing at the Vendome during the 1920s and continued long after.[92] His marriage to her lasted four years; they divorced in 1942. Louis then married Lucille Wilson, a singer at the Cotton Club in New York, in October 1942. They remained married until his death in 1971.[93]

Armstrong's marriages never produced any offspring.[94] However, in December 2012, 57-year-old Sharon Preston-Folta claimed to be his daughter from a 1950s affair between Armstrong and Lucille "Sweets" Preston, a dancer at the Cotton Club.[95] In a 1955 letter to his manager, Joe Glaser, Armstrong affirmed his belief that Preston's newborn baby was his daughter, and ordered Glaser to pay a monthly allowance of $400 ($5,058 in 2021 dollars[96]) to mother and child.[97]

Armstrong was noted for his colorful and charismatic personality. His autobiography vexed some biographers and historians, as he had a habit of telling tales, particularly of his early childhood when he was less scrutinized, and his embellishments of his history often lack consistency.[98]

In addition to being an entertainer, Armstrong was a leading personality of the day. He was beloved by an American public that gave even the greatest African American performers little access beyond their public celebrity, and he was able to live a private life of access and privilege afforded to few other African Americans during that era.[98]

He generally remained politically neutral, which at times alienated him from members of the black community who looked to him to use his prominence with white America to become more of an outspoken figure during the civil rights movement. However, he did criticize President Eisenhower for not acting forcefully enough on civil rights.[98]

The trumpet is a notoriously hard instrument on the lips, and Armstrong suffered from lip damage over much of his life. This was due to his aggressive style of playing and preference for narrow mouthpieces that would stay in place more easily, but which tended to dig into the soft flesh of his inner lip. During his 1930s European tour, he suffered an ulceration so severe that he had to stop playing entirely for a year. Eventually he took to using salves and creams on his lips and also cutting off scar tissue with a razor blade. By the 1950s, he was an official spokesman for Ansatz-Creme Lip Salve.[99]

During a backstage meeting with trombonist Marshall Brown in 1959, Armstrong received the suggestion that he should go to a doctor and receive proper treatment for his lips instead of relying on home remedies, but he did not get around to arranging it until the final years of his life, by which point his health was failing and doctors considered surgery too risky.[100]

Also in 1959, Armstrong was hospitalized for pneumonia while on tour in Italy. Doctors were concerned about his lungs and heart, but by June 26 he rallied.[101]

The nicknames "Satchmo" and "Satch" are short for "Satchelmouth". The nickname has many possible origins.[98] The most common tale that biographers tell is the story of Armstrong as a young boy in New Orleans dancing for pennies. He scooped the coins off the street and stuck them into his mouth to prevent bigger children from stealing them. Someone dubbed him "satchel mouth" for his mouth acting as a satchel. Another tale is that because of his large mouth, he was nicknamed "satchel mouth" which was shortened to "Satchmo".[98]

Early on he was also known as "Dipper", short for "Dippermouth", a reference to the piece Dippermouth Blues[102] and something of a riff on his unusual embouchure.

The nickname "Pops" came from Armstrong's own tendency to forget people's names and simply call them "Pops" instead. The nickname was turned on Armstrong himself. It was used as the title of a 2010 biography of Armstrong by Terry Teachout.[98]

After a competition at the Savoy, he was crowned and nicknamed "King Menelik", after the Emperor of Ethiopia, for slaying "ofay jazz demons".[103]

Armstrong always celebrated his heritage as an African American man from a poor New Orleans neighborhood and tried to avoid what he called "putting on airs". Many younger black musicians criticized Armstrong for playing in front of segregated audiences and for not taking a strong enough stand in the American civil rights movement.[104] When he did speak out, it made national news, including his criticism of President Dwight D. Eisenhower, calling him "two-faced" and "gutless" because of his inaction during the conflict over school desegregation in Little Rock, Arkansas in 1957. As a protest, Armstrong cancelled a planned tour of the Soviet Union on behalf of the State Department saying, "The way they're treating my people in the South, the government can go to hell"; he could not represent his government abroad when it was in conflict with its own people.[105][106] The FBI kept a file on Armstrong for his outspokenness about integration.[107]

When asked about his religion, Armstrong answered that he was raised a Baptist, always wore a Star of David, and was friends with the pope.[108] He wore the Star of David in honor of the Karnoffsky family who took him in as a child and lent him money to buy his first cornet. He was baptized a Catholic in the Sacred Heart of Jesus Church in New Orleans,[108] and he met Pope Pius XII and Pope Paul VI.[98]

Armstrong was concerned with his health. He used laxatives to control his weight, a practice he advocated both to acquaintances and in the diet plans he published under the title Lose Weight the Satchmo Way.[98] Armstrong's laxative of preference in his younger days was Pluto Water, but when he discovered the herbal remedy Swiss Kriss, he became an enthusiastic convert,[98] extolling its virtues to anyone who would listen and passing out packets to everyone he encountered, including members of the British Royal Family. Armstrong also appeared in humorous, albeit risqué, cards that he had printed to send out to friends. The cards bore a picture of him sitting on a toilet—as viewed through a keyhole—with the slogan "Satch says, 'Leave it all behind ya!'"[109] The cards have sometimes been incorrectly described as ads for Swiss Kriss.[110] In a live recording of "Baby, It's Cold Outside" with Velma Middleton, he changes the lyric from "Put another record on while I pour" to "Take some Swiss Kriss while I pour".[111] His laxative use began as a child when his mother would collect dandelions and peppergrass around the railroad tracks to give to her children for their health.[112]

Armstrong was a heavy marijuana smoker for much of his life and spent nine days in jail in 1930 after being arrested outside a club for drug possession. He described marijuana as "a thousand times better than whiskey".[113]

The concern with his health and weight was balanced by his love of food, reflected in such songs as "Cheesecake", "Cornet Chop Suey",[114] and "Struttin' with Some Barbecue", though the latter was written about a fine-looking companion, and not food.[115] He kept a strong connection throughout his life to the cooking of New Orleans, always signing his letters, "Red beans and ricely yours ...".[116]

A fan of Major League Baseball, he founded a team in New Orleans that was known as Raggedy Nine and transformed the team into his Armstrong's "Secret Nine Baseball".[117]

Armstrong's gregariousness extended to writing. On the road, he wrote constantly, sharing favorite themes of his life with correspondents around the world. He avidly typed or wrote on whatever stationery was at hand, recording instant takes on music, sex, food, childhood memories, his heavy "medicinal" marijuana use, and even his bowel movements, which he gleefully described.[118]

Louis Armstrong was not, as is often claimed, a Freemason. Although he is usually listed as being a member of Montgomery Lodge No. 18 (Prince Hall) in New York, no such lodge has ever existed. However, Armstrong stated in his autobiography that he was a member of the Knights of Pythias, which although real is not a Masonic group.[119] During the krewe's 1949 Mardi Gras parade, Armstrong presided as King of the Zulu Social Aid & Pleasure Club, for which he was featured on the cover of Time magazine.[120]

In his early years, Armstrong was best known for his virtuosity with the cornet and trumpet. Along with his "clarinet-like figurations and high notes in his cornet solos", he was also known for his "intense rhythmic 'swing', a complex conception involving ... accented upbeats, upbeat to downbeat slurring, and complementary relations among rhythmic patterns."[121] The most lauded recordings on which Armstrong plays trumpet include the Hot Five and Hot Seven sessions, as well as those of the Red Onion Jazz Babies. Armstrong's improvisations, while unconventionally sophisticated for that era, were also subtle and highly melodic. The solo that Armstrong plays during the song "Potato Head Blues" has long been considered his best solo of that series.[98][122]

Prior to Armstrong, most collective ensemble playing in jazz, along with its occasional solos, simply varied the melodies of the songs. Armstrong was virtually the first to create significant variations based on the chord harmonies of the songs instead of merely on the melodies. This opened a rich field for creation and improvisation, and significantly changed the music into a soloist's art form.[98]

Often, Armstrong re-composed pop-tunes he played, simply with variations that made them more compelling to jazz listeners of the era. At the same time, however, his oeuvre includes many original melodies, creative leaps, and relaxed or driving rhythms. Armstrong's playing technique, honed by constant practice, extended the range, tone and capabilities of the trumpet. In his records, Armstrong almost single-handedly created the role of the jazz soloist, taking what had been essentially a collective folk music and turning it into an art form with tremendous possibilities for individual expression.[98]

Armstrong was one of the first artists to use recordings of his performances to improve himself. Armstrong was an avid audiophile. He had a large collection of recordings, including reel-to-reel tapes, which he took on the road with him in a trunk during his later career. He enjoyed listening to his own recordings, and comparing his performances musically. In the den of his home, he had the latest audio equipment and would sometimes rehearse and record along with his older recordings or the radio.[123]

As his music progressed and popularity grew, his singing also became very important. Armstrong was not the first to record scat singing, but he was masterful at it and helped popularize it with the first recording on which he scatted, "Heebie Jeebies". At a recording session for Okeh Records, when the sheet music supposedly fell on the floor and the music began before he could pick up the pages, Armstrong simply started singing nonsense syllables while Okeh President E.A. Fearn, who was at the session, kept telling him to continue. Armstrong did, thinking the track would be discarded, but that was the version that was pressed to disc, sold, and became an unexpected hit. Although the story was thought to be apocryphal, Armstrong himself confirmed it in at least one interview as well as in his memoirs.[124] On a later recording, Armstrong also sang out "I done forgot the words" in the middle of recording "I'm A Ding Dong Daddy From Dumas".

Such records were hits and scat singing became a major part of his performances. Long before this, however, Armstrong was playing around with his vocals, shortening and lengthening phrases, interjecting improvisations, using his voice as creatively as his trumpet.[98] Armstrong once told Cab Calloway that his scat style was derived "from the Jews rockin", an Orthodox Jewish style of chanting during prayer.[125][126]

Armstrong was a gifted composer who wrote more than fifty songs, some of which have become jazz standards (e.g. "Gully Low Blues", "Potato Head Blues" and "Swing That Music").

During his long career he played and sang with some of the most important instrumentalists and vocalists of the time; among them were Bing Crosby, Duke Ellington, Fletcher Henderson, Earl Hines, Jimmie Rodgers, Bessie Smith and, perhaps most famously, Ella Fitzgerald. His influence upon Crosby is particularly important with regard to the subsequent development of popular music. Crosby admired and copied Armstrong, as is evident on many of his early recordings, notably "Just One More Chance" (1931).[98] The New Grove Dictionary of Jazz describes Crosby's debt to Armstrong in precise detail, although it does not acknowledge Armstrong by name:

Crosby ... was important in introducing into the mainstream of popular singing an Afro-American concept of song as a lyrical extension of speech ... His techniques—easing the weight of the breath on the vocal cords, passing into a head voice at a low register, using forward production to aid distinct enunciation, singing on consonants (a practice of black singers), and making discreet use of appoggiaturas, mordents, and slurs to emphasize the text—were emulated by nearly all later popular singers.

Armstrong recorded two albums with Ella Fitzgerald, Ella and Louis and Ella and Louis Again, for Verve Records. The sessions featured the backing musicianship of the Oscar Peterson Trio with drummer Buddy Rich on the first album and Louie Bellson on the second. Norman Granz then had the vision for Ella and Louis to record Porgy and Bess.

His two recordings for Columbia Records, Louis Armstrong Plays W.C. Handy (1954) and Satch Plays Fats (all Fats Waller tunes) (1955), were both being considered masterpieces, as well as moderately well selling. In 1961, the All Stars participated in two albums, The Great Summit and The Great Reunion (now together as a single disc) with Duke Ellington. The albums feature many of Ellington's most famous compositions (as well as two exclusive cuts) with Duke sitting in on piano. His participation in Dave Brubeck's high-concept jazz musical The Real Ambassadors (1963) was critically acclaimed and features "Summer Song", one of Armstrong's most popular vocal efforts.

Louis Armstrong in 1966

In the week beginning May 9, 1964, his recording of the song "Hello, Dolly!" went to number one. An album of the same title was quickly created around the song, and also shot to number one, knocking The Beatles off the top of the chart. The album sold very well for the rest of the year, quickly going "Gold" (500,000). His performance of "Hello, Dolly!" won for best male pop vocal performance at the 1964 Grammy Awards.

Armstrong had nineteen "Top Ten" records[127] including "Stardust", "What a Wonderful World", "When The Saints Go Marching In", "Dream a Little Dream of Me", "Ain't Misbehavin'", "You Rascal You", and "Stompin' at the Savoy". "We Have All the Time in the World" was featured on the soundtrack of the James Bond film On Her Majesty's Secret Service, and enjoyed renewed popularity in the UK in 1994 when it was featured on a Guinness advertisement. It reached number 3 in the charts on being re-released.

In 1964, Armstrong knocked The Beatles off the top of the Billboard Hot 100 chart with "Hello, Dolly!", which gave the 63-year-old performer a U.S. record as the oldest artist to have a number one song. His 1964 song "Bout Time" was later featured in the film Bewitched.[98]

In February 1968, he appeared with Lara Saint Paul on the Italian RAI television channel where he performed "Grassa e Bella", a track he sang in Italian for the Italian market and C.D.I. label.[128]

In 1968, Armstrong scored one last popular hit in the UK with "What a Wonderful World", which topped the British charts for a month. Armstrong appeared on the October 28, 1970, Johnny Cash Show, where he sang Nat King Cole's hit "Ramblin' Rose" and joined Cash to re-create his performance backing Jimmie Rodgers on "Blue Yodel No. 9".

Armstrong enjoyed many types of music, from blues to the arrangements of Guy Lombardo, to Latin American folksongs, to classical symphonies and opera. He incorporated influences from all these sources into his performances, sometimes to the bewilderment of fans who wanted him to stay in convenient narrow categories. Armstrong was inducted into the Rock and Roll Hall of Fame as an early influence. Some of his solos from the 1950s, such as the hard rocking version of "St. Louis Blues" from the WC Handy album, show that the influence went in both directions.[98]

Armstrong was posthumously awarded the Grammy Lifetime Achievement Award in 1972 by the Academy of Recording Arts and Sciences. This Special Merit Award is presented by vote of the Recording Academy's National Trustees to performers who, during their lifetimes, have made creative contributions of outstanding artistic significance to the field of recording.[138]

Recordings of Armstrong were inducted into the Grammy Hall of Fame, which is a special Grammy award established in 1973 to honor recordings that are at least 25 years old, and that have "qualitative or historical significance".[139][140]

The Rock and Roll Hall of Fame listed Armstrong's West End Blues on the list of 500 songs that shaped Rock and Roll.[141]

In 1995, the U.S. Post Office issued a Louis Armstrong 32-cent commemorative postage stamp.

In 1999 Armstrong was nominated for inclusion in the American Film Institute's 100 Years ... 100 Stars.[143]
