Who was James Carroll?

Major James Carroll was a US Army physician.

Carroll was born in England. He moved to Canada in 1874, and enlisted in the U.S. Army in 1874. He graduated with an M.D. from the University of Maryland in 1891. In 1900 he served as an American physician and a member of the Yellow Fever Commission in Cuba, along with Walter Reed, Jesse William Lazear, and Aristides Agramonte. He and Lazear subjected themselves to the bite of infectious mosquitoes to test the theory that mosquitoes were carriers of yellow fever. The infection he contracted eventually killed him.
