Cotton Mather, FRS (February 12, 1663 – February 13, 1728; A.B. 1678, Harvard College; A.M. 1681, honorary doctorate 1710, University of Glasgow) was a socially and politically influential New England Puritan minister, prolific author, and pamphleteer. Known for his vigorous support for the Salem witch trials, he also left a scientific legacy due to his hybridization experiments and his promotion of inoculation for disease prevention. He was subsequently denied the Presidency of Harvard College which his father, Increase, had held.
