text: She was the daughter of Lauritz J. Dorenfeldt (1863–1932), an engineer who was educated in Berlin, and the granddaughter of businessman Lauritz Dorenfeldt Jenssen (1837–1899). Her mother was Aagot Bødtker (1869–1963). Margot was born 2 October 1895 in Worms, Germany, when her family was there; her father was working on assignment as technical director of a cellulose factory.
  Margot Dorenfeldt was the second woman to enroll at the Norwegian Institute of Technology (NTH) after Aslaug Urbye (who enrolled in 1910, but never completed her studies). In 1919, Dorenfeldt became the first woman to graduate from NTH. While in college, she was active in student debates and made critical comments about her fellow engineers and their record of participation in social politics.
