Shprintzen AD. The Vegetarian Crusade: The Rise of an American Reform Movement, 1817-1921. University of North Carolina Press, 2013.
A fascinating account of the nineteenth-century origins of the vegetarian social movement to improve American morality and health. The book stops in 1921 when the Vegetarian Society disbanded, but that movement’s legacy is today’s passionate vegetarians, who comprise a vital part of the current movement to improve food systems and the health of people and the planet.
