Albert Leffingwell

Born in Aurora, New York, in 1845, Albert Leffingwell was an American physician, author, and social reformer. He studied medicine after serving in the Civil War and went on to write widely on ethics, health, and social questions.

He is best remembered for his books and pamphlets on vivisection, in which he criticized cruel animal experimentation while arguing for restraint and legal oversight rather than careless excess. His work made him an important voice in humane reform, and he was also active in broader debates about food safety and public welfare.

Leffingwell wrote in a direct, persuasive style meant for general readers as well as reform-minded professionals. He died in 1916, leaving behind a body of work that reflects the moral and medical controversies of the late nineteenth and early twentieth centuries.
