Rumford biscuit cutter. 19th-20th century, American. Round metal biscuit cutter. Co-founding the Rumford Baking Powder Co. in 1859, Eben Norton Horsford (1818-1893) graduated from Rensselear Polytechnic, NY in 1838 as a civil engineer, became a chemist and in 1847 was honored by being selected the Rumford professor at Harvard. He invented Horsford's Cream of Tartar Substitute, the first calcium phosphate baking powder. Hulman & Co. purchased the Rumford Chemical Works of East Providence, Rhode Island, in 1950. In 2000, the company was renamed Clabber Girl Baking Powder Co. Baking powder works as a gas when in contact with liquids. Rumford doesn't use alum, and reacts with heat.
