Anton Walter Freud (3 April 1921 – 8 February 2004) was a chemical engineer and a member of the Royal Pioneer Corps and the British Special Operations Executive.
After leaving Vienna in March 1938,[1] Freud's parents separated, and he and his father went to Britain whilst his mother and sister Sophie went to Paris before emigrating to the USA.
He was recruited by British Hydrocarbons based in London in 1957, which after a series of mergers became part of BP Chemicals, where he remained until his retirement at the age of 55 in 1977.
[6] In 1994 he returned to Vienna for the first time since his enforced exile as a guest of the Austrian government, which marked his achievement in liberating the Zeltweg airfield by hosting a dinner in his honour.
[9] In 2022 Spiegel TV produced a docu-drama based on Freud's work with the War Crimes Investigation Unit: Nazijäger – Reise in die Finsternis.
