Forced to leave Alsace during the Franco-Prussian War of 1870, Théodore Grimmeisen, head of a family barrel-making business, took his know-how with him to Paris. The Factory thus came to be built on a piece of wasteland in the 11th arrondissement of Paris, at 5 passage Piver. His son, also called Théodore, for his part turned his attention to the development of rubber as a material for making stoppers, with a view to replacing the traditionally-used cork. It was while working with this revolutionary material that he had the idea of making heels for shoemakers. The factory thus went on to enjoy further expansion, thanks to rubber and footwear. Under the Colibri brand, rotating heels, clogs, sandals, boots and sneakers emerged.
