Arm and Hammer started as John Dwight and Company in 1846 when John Dwight and Austin Church used their sodium bicarbonate in their kitchen. They formerly made the Cow Brand trademark on their baking soda. In 1886, Austin retired and his two sons succeeded in selling Arm and Hammer Baking Soda through their name Church and Co as a competing company to the John Dwight Company which continued selling Cow Brand baking soda.
