William Crawford Gorgas KCMG was a United States Army physician and 22nd Surgeon General of the U.S. Army (1914–1918). He is best known for his work in Florida, Havana and at the Panama Canal in abating the transmission of yellow fever and malaria by controlling the mosquitoes that carry these diseases, for which he used the discoverments made by the cuban doctor Carlos J. Finlay. At first, Finlay's strategy was greeted with considerable skepticism and opposition to such hygiene measures. However, the measures Gorgas put into practice as the head of the Panama Canal Zone Sanitation Commission saved thousands of lives and contributed to the success of the Canal's construction.
