Adele Duttweiler (née Bertschi; 29 December 1892 – 27 May 1990) was a Swiss philanthropist. She was married to Gottlieb Duttweiler, founder of the Migros concern and the LdU political party.
Early life and education
Duttweiler was born Adele Bertschi on 29 December 1892 in Horgen on Lake Zürich, one of six children, to Samuel Bertschi (1821–1901), a retired silk ribbon manufacturer, and Marie Bertschi (née Antille). She had four half-siblings in America and five more siblings in Switzerland, of which only three reached adulthood.
Her paternal family originally hailed from Dürrenäsch.[1] In 1854, her father emigrated to the United States aboard the North Wind. Together with his first wife he settled in New York City, where he founded one of the first silk manufacturing companies, employing several hundred people at three locations in Manhattan, including on Broome Street in Lower Manhattan.[2]
