James Jensen was a machinist at Hanford, Washington from September 1944 to the end of the war. Jensen's security clearance allowed him to machine parts and complete various tasks for the maintenance of the nuclear piles. Jensen gained worldwide fame after the war as an acclaimed paleontoligist with Brigham Young University. His numerous expeditions in search of dinsosaur remains earned him the nickname "Dinosaur Jim."
