In the United States, Reverend William Metcalfe (1788–1862), a pacifist and a prominent member of the Bible Christian Church, preached vegetarianism. He and Sylvester Graham, the mentor of the Grahamites and inventor of the Graham crackers, were among the founders of the American Vegetarian Society in 1850. In 1838, Dr. William Alcott published "Vegetable Diet: As Sanctioned by Medical Men, and by Experience in All Ages." The book was reprinted in 2012, and journalist Avery Yale Kamila called it "a seminal work in the cannon of American vegetarian literature."
