Karl Robin Bendetsen (October 11, 1907 – June 28, 1989) was born in Aberdeen, Washington. His parents, Albert M. and Anna Bendetson, were first-generation American citizens, and his grandparents were Jewish immigrants from Eastern Europe. Karl changed the spelling of his last name during early 1942, and would later make written claims to descent from Danish lumbermen who had come to America as early as 1670.
Bendetsen is remembered primarily for his role as architect of the internment of Japanese Americans during World War II (a role he tried to downplay in later years).
Bendetson (as he was then known) enlisted in the Washington National Guard, at the age of fourteen. While this was well below legal age, the National Guard turned a blind eye to the many young men who desired to enlist while who were still in—or, as in Bendetsen's case, had yet to enter—high school.
As he matured, Karl entered Army ROTC, eventually taking an infantry commission in the Army Reserve.
Bendetson, now a major, was on the administrative staff of Judge Advocate General Major General Allen W. Guillion.
In early September 1941, Bendetson was sent to Hawaii to discuss the need to intern enemy aliens in case of war. He stated in his notes that there were 134,000 American citizens of Japanese descent in the islands, and worried that "good Americans" might "give Japs the benefit of the doubt" for economic reasons.
In November, Bendetson was sent to take over an aircraft plant in New Jersey, as part of a plan by President Franklin D. Roosevelt to boost production of factories making materiel needed by Great Britain.
Major Bendetson was given this assignment after having written the orders for seizure and strike-breaking at a North American Aviation plant, but the army had taken charge of the Air Associates plant in October, prior to his arrival. In later years, however, Bendetsen would describe a wild scene of standing on his overturned car to face down the "mass" of strikers who had blocked his way into the plant.
The strike settled, Bendetson was back at his own desk in early December.
