Which dietary reformer inspired the name of the graham cracker?

The graham cracker was named for Sylvester Graham, a 19th-century American dietary reformer and Presbyterian minister. His preaching inspired graham flour, graham bread, and the cracker that eventually carried his name.

Graham promoted vegetarianism, temperance, and bread made from coarsely ground whole wheat. He believed that a simple, natural diet supported physical and moral health. His followers, known as Grahamites, helped spread these ideas during the popular health-reform movements of the 1830s.

The earliest graham wafers were plain, unsifted, and sugarless—very different from the sweet honey- or cinnamon-flavored crackers commonly sold today. Graham himself did not invent a modern commercial brand or profit from the products associated with his teachings.

Commercial production developed later. The National Biscuit Company, now associated with Nabisco, began mass-producing graham crackers in 1898. Today they are used as snacks and as ingredients in pie crusts, cheesecakes, and s’mores. The name therefore honors Graham’s dietary influence, not a company founder or a cereal manufacturer.
