Charles Lathrop Parsons

After graduation, Parsons worked briefly as assistant chemist at the New Hampshire Agricultural Experiment Station in Hanover, New Hampshire.[1] In 1889 he became an instructor of chemistry at the New Hampshire Land Grant College[2] (now the University of New Hampshire). He was promoted to the new position of associate professor of chemistry in 1890. He became professor of general and analytical chemistry in 1891[1] and professor of inorganic chemistry in 1903.[2] He supervised the transition of the chemistry department during New Hampshire College's move from Hanover to Durham, New Hampshire, in 1893.[1] From 1909 to 1911 he served as head of the department of chemistry.[2]

Parsons' research dealt with analysis of minerals, ores and radioactive materials. He was the co-author of Mineralogy, Crystallography and Blowpipe Analysis (1900)[2] with A. J. Moses, which went into multiple editions.[4] He was the author of The Chemistry and Literature of Beryllium (1909),[2][5] of Fuller's Earth (1913),[6] and other titles. He was recognized for his work on beryllium, for which he won the William H. Nichols Medal in 1905.[7][8] In addition to his research, Parsons took an active interest in the history of the American Revolution and published a book in 1903 about the Capture of Fort William and Mary.[9]

On September 1, 1912, Parsons became the chief mineral chemist at the U.S. Bureau of Mines in Washington, D.C.[1][8] In 1913, Parsons helped to organize the National Radium Institute to study the extraction of radium from carnotite ores[1] and create a domestic process for its extraction, rather than exporting the raw material and importing radium.[2] He was deeply interested in the use of radium to treat cancerous tumors.[1]

In 1916, during World War I, Parsons was transferred to the War Department, with the position of chief engineer. He was sent to Europe to study the fixation of nitrogen and oxidation of ammonia, which were important for the production of fertilizer and explosives. At his recommendation, four factories were built, entering production after the end of the war.[1]

Parsons was also responsible for arranging for a census of American chemists. When the United States entered the war in April 1917, selected chemists were released from military service to carry out research on projects considered important to the war effort. Parsons helped to organize the Chemical Warfare Service of the US Army. In 1919, after the end of the war, Parsons left the Bureau of Mines.[1]

Parsons became a member of the American Chemical Society (ACS) when he attended the World Congress of Chemists at the Columbian Exposition of 1893 in Chicago.[1][2] From 1907 until 1919, Parsons was part-time secretary of the American Chemical Society,[1] succeeding William A. Noyes.[2] From 1919 to 1946, Parsons was full-time executive secretary of the ACS, its chief administrative officer, in charge of its day-to-day operations. He retired on December 31, 1945, after the end of World War II.[1]

Parsons was closely involved, along with Marston T. Bogert, in establishing a new structure for the ACS. He helped to transform it from a New York State Corporation into a national organization based in Washington, D.C. He was also involved with the creation of a number of divisions, organized around specialized groups, beginning with Industrial Chemists and Chemical Engineers.[1] He is credited with substantially expanding the association's membership and its publications.[10] Under his leadership, its roster expanded from 3000 members in 1908 to 40,000 in 1945.[1] The number of journals published by the society increased from two to eight.[10] The annual budget of the organization expanded from several thousand dollars to 1.5 million dollars.[2]

In addition, Parsons served as secretary of Section C of the American Association for the Advancement of Science (AAAS) from 1904 to 1908. He served as vice president for America of the International Union of Pure and Applied Chemistry (IUPAC), from 1919 to 1922.[11]
