American astronomer and author of The Case for the UFO (1955). Connected to the Varo annotated-edition correspondence and the Philadelphia Experiment lore. Found dead in 1959 in his car in Florida; ruled suicide.
Morris K. Jessup was an astronomer, researcher, and author of the pioneering 1955 book 'The Case for the UFO'. He is deeply intertwined with UAP lore due to his connection to the alleged Philadelphia Experiment, having received bizarre letters describing military teleportation. Jessup's key contribution was his early, scientifically grounded argumentation for the existence of anomalous aerospace phenomena and the need for rigorous study. He died in 1959 from an apparent suicide, though his death remains a subject of intense conspiracy theories suggesting he was silenced by government agents. He represents one of the earliest academic figures to fully dedicate himself to unraveling the UFO mystery.
