Carl Leavitt Hubbs

He was born in Williams, Arizona. He was the son of Charles Leavitt and Elizabeth (née Goss) Hubbs. His father had a wide variety of jobs (farmer, iron mine owner, newspaper owner). The family moved several times before settling in San Diego where he got his first taste of natural history.[1] After his parents divorced in 1907, he lived with his mother, who opened a private school in Redondo Beach, California. His maternal grandmother Jane Goble Goss, one of the first female doctors, showed Hubbs how to harvest shellfish and other sea creatures.

One of his teachers, impressed by Hubbs's abilities in science, recommended that he study chemistry at the University of Berkeley. The family moved once more to Los Angeles. In Los Angeles, George Bliss Culver, one of the many volunteers of David Starr Jordan, encouraged Hubbs to abandon his study of birds[2] and instead to study fish, particularly those fish that inhabited the rivers of Los Angeles, which at that time had not been well researched. Hubbs completed his studies at Stanford University, following particularly the ichthyologist Charles Henry Gilbert, a disciple of Jordan. Gilbert became Hubbs's mentor and gave him the responsibility of caring for a collection of fish from Stanford. During this same period, Hubbs met John Otterbein Snyder, another disciple of Jordan. Hubbs obtained his BA in 1916 and his master's degree in 1917.

From 1917 until 1920 Hubbs served as the assistant curator of fish, amphibians, and reptiles at the Field Museum of Natural History in Chicago. He married Laura Cornelia Clark on June 15, 1918, with whom he had three children. His wife, who had also studied at Stanford, having received her BA in 1915 and her master's degree in 1916, taught math.

In 1920, he took the position of curator of fish at the Museum of Zoology at the University of Michigan, a position he held for 24 years. In 1927, while working at the University of Michigan, he received his Ph.D., writing his dissertation on The Consequences of Structural Modifications of the Developmental Rate in Fishes Considered in Reference to Certain Problems of Evolution. Hubbs himself along with members of team and students contributed to the enrichment of the museum's collection. In 1929, he participated in an academic trip to Java where he collected five tons of specimens. Hubbs began to study hybridization among different species of fish.

In addition to his position as conservator, Hubbs was the first director of the Institute for Fisheries Research in the Department of Conservation of Michigan (1930–1935). In this role, he conducted research on the diverse inventory of regional fauna, mortality, water pollution, growth and predation. During his stay at the University of Michigan, Hubbs issued more than 300 publications, almost entirely devoted to fish. His studies were not confined to the United States because he also studied a large collection of fish from Japan.

From 1944 to 1969, Hubbs taught biology at the Scripps Institution of Oceanography at the University of California San Diego in La Jolla, where he replaced Francis Bertody Sumner. From 1969 to 1979 he served as professor emeritus. He accepted the post for the new research opportunities it opened. Still, the position offered a lower salary and the rules prevented him from hiring his wife.[3]

The restrictions of World War II forced the Scripps Institution to rent his research boat to the army, significantly restricting his research opportunities. During the summer of 1946, Errol Flynn, son of a marine biologist, offered Hubbs to accompany him during a cruise aboard his yacht, the Zaca. The results weren't great but Hubbs discovered high levels of endemism of species of Guadeloupe.

In the years following the war, Hubbs began doing research in the field of commercial and recreational fishing. He observed changes in population patterns depending on the fluctuation in temperatures in the Pacific Ocean. He began studies of ancient climates through such tools as dating mollusk shells. His research led to the founding of a laboratory in 1957 to provide dating for archaeological and geological samples. He bequeathed his collection to San Diego's Archaeological Museum of Man in 1973.

Hubbs was married to mathematician Laura Cornelia Clark Hubbs, sister of ichthyologist Frances Naomi Clark. They met on a field trip of the Stanford Natural History Club. The couple worked there and had three children who survived to adulthood, Frances (born in 1919), Clark born in 1921 and Earl born in 1922. Frances, who married the ichthyologist Robert Rush Miller, and Clark both became ichthyologists, while Earl became a headteacher.[4]

He died June 30, 1979, in La Jolla, California. Hubbs SeaWorld Research Institute was named after him.
