Norwegian resistance member, engineer, and business founder. During the German occupation of Norway from 1940 he was involved in the Norwegian resistance movement where he cooperated with fellow engineers Odd Dahl and Helmer H. Dahl to wiretap German forces. This was discovered and Simonsen was arrested by Gestapo, but admitted to Ullevål Hospital from which he escaped. He fled to the United Kingdom, where he started working at the Radio Production Unit of the British War Office. He developed the shortwave radio "Sweetheart."
After the war he was hired as a technical consultant of the Norwegian High Command. In 1947 he started the company Simonsen Radio in Oslo, and in 1957 the company Simonsen & Mustad followed in Horten. In 1970 he started Simonsen Elektro in Oslo and Simonsen Elektro Løkken at Løkken Verk. These companies produced automatic cell phones in the NMT 450 system and were leading in the Norwegian market until the 1980s.
Simonsen died on 4 December 2003 in Oslo, Norway, aged 90.
