William Crawford Gorgas KCMG (October 3, 1854 – July 3, 1920) 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. At the time, his strategy was greeted with considerable skepticism and opposition to such hygiene measures. However, the measures he 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. He was a Georgist and argued that adopting Henry George's popular 'Single Tax' would be a way to bring about sanitary living conditions, especially for the poor. Early life and education Born in Toulminville, Alabama, Gorgas was the first of six children of Josiah Gorgas and Amelia Gayle Gorgas. After studying at The University of the South and Bellevue Hospital Medical College, Dr. Gorgas was appointed to the US Army Medical Corps in June 1880. Military career He was assigned to three posts—Fort Clark, Fort Duncan, and Fort Brown—in Texas. While at Fort Brown (1882–84), Gorgas survived an episode of yellow fever. He met Marie Cook Doughty who also contracted the disease at the same place and time. Coffins were designated for them both, but they recovered together, forming a bond and soon married. In 1898, after the end of the Spanish–American War, Gorgas was appointed Chief Sanitary Officer in Havana, where he and Robert Ernest Noble worked to eradicate yellow fever and malaria. Gorgas capitalized on the momentous work of another Army doctor, Major Walter Reed, who had built much of his work on the insights of Cuban doctor, Carlos Finlay, to prove the mosquito transmission of yellow fever. Through his efforts draining both the Aedes mosquito vector breeding ponds and quarantining of yellow fever patients in screened service rooms, cases in Havana plunged from 784 to zero with a year. He won international fame battling the illness, which was then the scourge of tropical and sub-tropical climates. He worked in Florida, later in Havana, Cuba, and finally, in 1904, at the site of the construction of the Panama Canal. As chief sanitary officer on the canal project, Gorgas implemented far-reaching sanitary programs, including the draining of ponds and swamps, fumigation, use of mosquito netting,
