Carrosserie Gaston Grümmer was a French coachbuilder based in Clichy, a suburb of Paris. Founded on July 30, 1924, Grümmer designed and produced individual bodies for luxury automobiles in the period between the world wars. In the 1930s, Grümmer was considered a pioneer of lightweight construction and aerodynamics. The company was founded by Gaston Grümmer. He came from a family that had lived in Aachen since the 17th century. His grandfather Friedrich Joseph Grümmer moved to Brussels in the 19th century, where he set up a saddlery business that specialized in furnishing high-quality carriages. He later moved to Paris. His son Antoine Joseph worked for the long-established Paris tableware manufacturer Morel since at least the turn of the century. In 1919, Antoine Grümmer’s sons, including Gaston, took over the Morels business and renamed it Établissements Grümmer. In the early years, the Grümmer brothers still manufactured high-quality, individual interior fittings for carriages, but then made the switch to automobiles.
