Martin Siem

Ole Martin Siem[1][2] (6 January 1915 – 3 November 1996) was a Norwegian businessman and World War II resistance member.

He was born in Horten as a son of naval commander Ole Siem (1882–1979) and Marie Augusta Ursin Holm (1888–1961).

[3] When World War II reached Norway with the Nazi German invasion, Siem fought for his country in the Battle of Hegra Fortress.

His information on the Port of Oslo became especially important for Norwegian ship saboteurs, such as Max Manus, Gregers Gram and Roy Nielsen.

[2] Siem helped Israel retrieve missile boats purchased and then embargoed by French president Charles de Gaulle in a Christmas Eve raid at Cherbourg Harbour in 1969.
