Colonel Fielding Hudson Garrison, MD (November 5, 1870 – April 18, 1935) was an acclaimed medical historian, bibliographer, and librarian of medicine. Garrison's An Introduction to the History of Medicine (1913) is a landmark text in this field.
Garrison was born in Washington, D.C. and received his A.B. in 1890 from the Johns Hopkins University and his M.D. in 1893 from Georgetown University. The son of U.S. Treasury Comptroller John Rowzee Garrison and noted Washington, D.C. civic volunteer Catherine Jane Jennie Davis, he married Clara Augusta Brown in 1910 in Washington, D.C. and they eventually had three daughters. (Garrison was brother-in-law — they married sisters in a double wedding — to Henry Campbell Black, author of "Black's Law Dictionary.)
Garrison joined the staff of the Army Medical Library as a clerk in 1891. (The AML was to become the National Library of Medicine many years after Garrison's death.) He became Assistant Librarian in 1899 and Principal Assistant Librarian in 1912. He joined the Officers Reserve Corps as a Major in 1917 (Lieutenant Colonel, 1918 and Colonel, 1920). Garrison was assigned to index medical literature. In this he worked closely with John Shaw Billings. He helped create and compile the Index-Catalogue of the Library of the Surgeon General's Office. His editorial responsibilities also included the Index Medicus, of which he was Associate Editor (1903–1912) and Editor (1912–1927). He was also Associate Editor of the Quarterly Cumulative Index Medicus for 1927–1929. Garrison wrote the first comprehensive treatise on the history of medicine and "gained recognition as the foremost American authority on the subject" (according to the Dictionary of American Biography). He prepared plans and collected material for the history of the U.S. Army Medical Department during World War I. In all, he served on staff at the AML for almost 40 years.
