Otto Sverdrup Engelschiøn

Otto Sverdrup Engelschiøn (30 October 1902 – 8 May 1982) was a Norwegian marketer, businessperson, resistance member and genealogist.

He was born in Kristiania as a son of consul-general Søren Dass Brodtkorb Sverdrup Engelschiøn (1867–1909) and Janka Hansen (1869–1935). In 1928 he married Gudrun Irgens Garmann.

Engelschiøn finished his secondary education in 1922 and graduated from the Royal Frederick University with the cand.jur. degree in 1926. He was an attorney from 1927, and also director of I. Sverdrup Engelschiøn which had the rights to distribute Swedish Tomten products in Norway. In 1929 it was merged with Norsk Barnengens Tekniske Fabrik. Engelschiøn spent the rest of his career in the company, from 1929 as director of the sales and marketing department and from 1948 to 1968 as co-owner. In 1940, however, Norway was invaded and occupied by Nazi Germany. Engelschiøn joined the resistance movement and was the head of intelligence in Milorg's District 13, Division 3 (Asker and Bærum) from 1943 to 1945. He received the Defence Medal 1940–1945 with rosette.
