George Soper

George Albert Soper II (2 February 1870 – 17 June 1948) was an American sanitation engineer and epidemiologist. He specialized in the investigation of water- and food-borne disease and urban sanitation, and is best known for identifying Mary Mallon (''Typhoid Mary'') as the first recognized asymptomatic carrier of typhoid fever in the United States.

Over a career that ranged from the Galveston hurricane of 1900 to the 1918–1919 influenza pandemic and early national cancer campaigns, Soper held senior positions in municipal and military public health, served as managing director of the American Society for the Control of Cancer (later the American Cancer Society), and wrote influential articles on epidemic control and waste disposal.
