The origin of the company A. Gutmann & Co. goes back to the year 1840 in Jebenhausen. There, the master weavers Abraham Gutmann, his brother-in-law Simon Raff and his cousin Isak Raff founded a hand weaving mill, which existed in Jebenhausen until 1861, when it was moved to Göppingen. With the relocation of the company to Göppingen, all three company owners also moved their residence to Göppingen. However, the company owners separated in the same year.
