Richard "Dick" Zeiner-Henriksen ( 1 August 1924 – 12 May 2016) was a Norwegian businessperson and resistance member during World War II.
On 9 April 1940 Nazi Germany invaded and occupied Norway as a part of World War II. Young Zeiner-Henriksen became a member of the Norwegian Independent Company 1 (Norwegian: Kompani Linge). From 1943 to 1944 he cooperated with Max Manus and Oslogjengen, and from 1944 to 1945 he participated in the Special Operations Executive operation GREBE in Dovrefjell and Rondane.
Among others, he participated in the May 1944 sabotage of Arbeidstjenesten's offices. He obtained copy of the door key to the address Wergelandsveien 3 (via an imprint in plastilina) together with Roy Nielsen. Nielsen was in charge of the strike towards Wergelandsveien 3, but the mission was called off because there were people present at the office. Zeiner-Henriksen joined Max Manus, Edvard Tallaksen and Gregers Gram to strike the address Kirkeveien 90. Zeiner-Henriksen was placed outside the building, tasked with ringing the doorbell in case of peril. As the three main saboteurs had spent one and a half-hour burning Arbeidstjenesten's documents, they heard the doorbell as well as shooting. Four people from Milorg had been placed throughout the area to assist with firepower in case enemies showed up. Three of the four guards (Lars Eriksen, Jon Hatland and Per Stranger-Thorsen) were captured and executed, whereas the fourth guard Hans-Peter Styren survived. Tallaksen, Gram and Zeiner-Henriksen escaped on foot whereas Manus stole a bike from a passer-by. Only Zeiner-Henriksen, Manus and Styren survived World War II. It later became clear that troops showed up because the Nazi collaborator Hans Eng stayed at the same address that day. The sabotage mission was portrayed in the 2008 film Max Manus. Zeiner-Henriksen was decorated with the Norwegian War Medal, the Defence Medal 1940–1945 and the British King's Medal for Courage in the Cause of Freedom.
