He was born in
Kristiania as a son of alcohol importer
Carl Schøyen Dysthe and Alfhild Dorothea Rachlew Dysthe. He had one older brother,
Sven, and the younger siblings Gunnar, Ingeborg and Helge. He
finished his secondary education in 1921, and took his education abroad, in commerce, wine and liquor production. From 1928 to 1930 they were involved in a major public case. On 4 May 1928 they wrote a letter to the
government, complaining that the state semi-monopoly
Vinmonopolet disfavorized their father's wine importing agency
Dysthe & Co. A scrutiny commission was set up to review Vinmonopolet's business practice. Vinmonopolet, on the other hand, sued the Dysthe brothers to have the complaints declared
null and void, but a year later, in April 1930, Vinmonopolet lost the legal case. The Dysthe brothers' defender was
Ole Røed. The case became a major scandal in the media as Vinmonopolet's role was unveiled. The board chairman
Hans Halvorsen, who was a brother-in-law of the Prime Minister
Johan Ludwig Mowinckel, had to resign together with board member
Trygve Wettre and three employees. From the 1930s the brothers were active in the Norwegian-Third Reich friendship society
Norsk-Tysk Selskap. He worked at
McKesson & Robbins. and was a board member of Dysthe & Co. ==World War II==
