Marman Products Company, Inc. of Inglewood, California, was a business established by Zeppo Marx (1901–1979) in 1941. Until 1933 he had been the Marx Brothers' straight man, and Marman Products made clamping devices and straps. During World War II, like many other companies Marman was involved in the war effort. As part of this, Marman Products produced the "Marman Clamp", used to support the atomic bombs carried on the Enola Gay. In 1948 the company also developed and marketed a short-lived 2-cylinder low-powered motorcycle brand, the "Marman Twin".
