# 877 - 5¢ Walter Reed: plate block - Scientist

Walter Reed was the American Army Medical Doctor who confirmed the theory that yellow fever was transmitted by mosquito and not through direct human contact. Reed's research work was conducted on human volunteers who allowed themselves to be deliberately infected with yellow fever. Although the experiments resulted in the deaths of Jesse Lazear and Clara Maas, among others, the results allowed for the successful completion of the Panama Canal. Scott 877 Walter Reed
