Carroll, James, 1854–1907, American bacteriologist and army surgeon, b. Woolwich, England, M.D. Univ. of Maryland, 1891. He went to Canada at 15 and later joined the U.S. army. A member of the Yellow Fever Commission under Walter Reed, he voluntarily submitted to the bite of an infected mosquito, contracted yellow fever, and recovered. This proved the mosquito to be the carrier of the disease. Carroll also proved that the infectious agent is a filterable virus.
