Sigurd Sverdrup

Sigurd Bernhard Sverdrup (1 June 1918 – 16 May 2008) was a Norwegian World War II resistance member.

Here he gained contact with Martin Siem, a worker at the mechanic yard Akers Mekaniske Verksted.

Siem was an informant regarding his workplace, whereas Sverdrup gained a direct channel to the executive of the Oslo Port Authority.

[2] Sverdrup was specifically tasked with coordinating naval intelligence in the Oslofjord, from Kristiansand in the west to Halden in the east.

RMO cooperated with XU and Milorg,[1] and information on the Port of Oslo became especially important for Norwegian ship saboteurs, such as Max Manus, Gregers Gram and Roy Nielsen.
