Although Jessup had a Master's degree in astronomy he worked most of his time as an automobile-parts salesman and a photographer.
He is mostly known for his pioneering ufological writings and his role in "uncovering" the so-called "Philadelphia Experiment"an alleged military experiment that is said to have been carried out by the U.S. Navy at the Philadelphia Naval Shipyard in Philadelphia, Pennsylvania some time around October 28, 1943. The U.S. Navy destroyer escort USS Eldridge was claimed to be rendered invisible (or "cloaked") to enemy devices.
