Major General William C. Gorgas was a U.S. Army physician and Surgeon General from 1914-1918 best known for his work controlling mosquitoes that transmit yellow fever and malaria. As chief sanitary officer for projects in Florida, Havana, and the Panama Canal, Gorgas implemented extensive sanitation programs including draining ponds and swamps and using mosquito netting. These measures were crucial in enabling the construction of the Panama Canal by preventing illness among thousands of workers. Gorgas received international acclaim for his contributions and an honorary knighthood shortly before his death in 1920.
