Albert Leffingwell, M.D. (1845–1916) was a physician, social reformer, and vocal advocate for vivisection reform. He authored many books bringing light to the cruel abuses of animal experimentation and calling for regulation. At the same time he sought middle ground between the antivivisection societies which called for the abolition of all experimentation and those who rejected any restraints. Leffingwell also was concerned with meat safety, believing that lax regulations, in particular allowing cancerous animals into the food chain, were responsible for increases in the incidence of cancer. He also served as the president of the American Humane Association.
He was born in 1845. He died in 1916.
