Adele Duttweiler  Adele Duttweiler (29 December 1892 – 27 July 1990) was a Swiss philanthropist and the wife of Gottlieb Duttweiler, founder of both the Migros group and the LdU political party. Adele Bertschi was born on 29 December 1892 in Horgen on Zürichsee lakeshore. Her mother was Maria, née Antille, her father was Samuel, who had emigrated to the US, where he founded a ribbon weaving mill. When his first wife died, he returned as a "made man" back to Switzerland. He married Maria Antille, who originates from the Canton of Valais. The couple moved to Horgen, where they acquired the "In Rüsler" farm where Adele grew up. Her father died when Adele was at the age of eight years. Adele's mother was described as a "purposeful and spirited woman who had to cope with all sorts of harassment after the early death of her man". She struggled successfully against all odds, a character trait that Adele owed to her mother. After primary school in Horgen, Adele graduated from the then usual "Welschlandjahr" for young women – a longer stay in western Switzerland to learn the French language, mostly as domestic help. She then worked as an employee of ETH Zürich in the seeds control department. As employee of ETH Zürich, Adele Bertschi drove daily by train from Horgen to Zürich. Around the year 1911, a "handsome, young, well-dressed man" from Rüschlikon began to sit down opposite the rather shy young acting 19-year-old woman, annoying Adele: "He looked at me with big eyes. I was not really happy, I was still almost a child. But probably just my reticence has irritated him not to give up." When his courtship seemed to show no result, he tried a hackney. As soon as he had learned to ride, he visited his beloved at her home in Horgen. Unfortunately, his appearance attracted more impression to Adele's mother and sister. The mother then invited the imposing but somewhat uncertain tab for lunch. Adele Duttweiler expressed concerns where they seemed attached to her, even in quite commercial matters. He listened to their advice, and his in-the-future-thinking was always added by "Adele's sense of the reality of the presence".
