Founded on 1 October 1906 by Wilhelm Reutter as Stuttgarter Carosserie und Radfabrik, the company became known for building limousine bodies during the 1920s.[1][2][3] In 1909 Wilhelm's brother Albert Reutter joins the company as a partner and commercial manager. Change of name to "Stuttgarter Karosseriewerk Reutter & Co.", owner W. & A. Reutter.[4] On July 24, 1909, the patent for a "folding roof with canopy, especially for motor vehicles" is filed.[5] This so-called "reform body" was a constructive forerunner of the convertible.[5] The result is bodies including interior fittings for almost all well-known manufacturers of the time, in particular Daimler-Benz (and predecessor) as well as the Chemnitzer Wanderer-Werke.[5] In 1919, the gradual conversion from individual production to mass production takes place.
