Griswold Manufacturing was founded in the mid-1860s by Matthew Griswold and John and Samuel Selden. Originally the Selden & Griswold Manufacturing Co., Griswold bought out the Selden family interests in 1884. Since then the company has changed hands several times, including being bought by its major competitor, Wagner Manufacturing Co., in 1957. In August 1969, the General Housewares Corp. acquired all rights to Griswold and Wagner.
