Gottlieb Duttweiler (15 August 1888 – 8 June 1962) was a Swiss businessman and politician, founder of both the Migros chain of grocery stores and the (LdU) party.
Duttweiler was born in Zürich. Starting with five vehicles in 1925, his Migros eventually opened stores and is today one of the main grocery chains in Switzerland. The original secret to his success was bringing daily necessities to the consumer by excluding the middlemen. As a result, many producers initially chose to boycott Migros, and Duttweiler's Migros would itself manufacture or package those missing products. In 1941 Gottlieb and his wife Adele Duttweiler transferred ownership of Migros to their customers, as a cooperative. Duttweiler also required that Migros contribute a percentage of profits (actual from the total revenue) to cultural, athletic, and hobby-related activities. This led to the Migros-club-schools and several hobby courses.
Duttweiler also founded the political party Landesring der Unabhängigen (national ring of independents).
Duttweiler died in Rüschlikon. The Gottlieb Duttweiler Institute was founded after his death.
