a member of the top management team ("Direktions-Sekretariat"). Between 1946 and 1950, he was in charge of passenger car testing. In 1954, he received Procuration responsibility on behalf of the company, and this was also the year in which he took over the Mercedes-Benz Museum. He died at Munich on 8 August 1957. He is buried in Stuttgart. Family Wilhelm married Elisabeth Theurer on 19 June 1928, in the teeth of opposition from his father voiced when they got engaged. Elisabeth was the daughter of Richard Theurer, General Director of G. Siegle & Co., a long-established Stuttgart manufacturer of dyes and colourings, and his wife Elisabeth Groß. By the date of his marriage, Wilhelm's father had been dead for nearly three months, but the marriage was nonetheless deemed morganatic, and he was required to renounce his right to the title Duke of Urach, Count of Württemberg. Headship of the noble family instead passed to his younger brother, Karl Gero, Duke of Urach. The marriage produced two recorded daughters, the elder of which, Elisabeth von Urach (b. 1932), obtained a doctorate in psychology and worked in a top job with Stuttgart's Education and Youth Counselling service. The younger daughter, Maria Christine von Urach (1933–1990), mirrored her father's career choice, with a successful 31-year career at Daimler-Benz, starting as an engineer and ending up in charge of Data Processing at Untertürkheim.
