Church & Dwight was founded by Dr. Austin Church, and his brother-in-law, John Dwight. Together, they went into the production and marketing of Baking Soda, a trade name for bicarbonate of soda.


James A. Church joined his father as a member of Church & Co. and adapted the famous ARM & HAMMER™ trademark – the arm of Vulcan, Roman mythological god of fire, with hammer in hand. Since then, this trademark has become one of the world’s most recognized logos – a symbol of the company’s tradition of integrity and quality.
