Josef Papp (1933? in Tatabánya, Hungary – April 1989 in Daytona Beach, Florida) was an engineer who was awarded U.S. patents related to the development of an engine, and also claimed to have invented a jet submarine.

Papp was issued several U.S. patents for these inventions, including his noble gas fuel mixture.[1]

The engine continues to be considered by many scientists as a hoax. Papp's poor physics theoretic background is demonstrated in the abstracts of the patents, which had been criticized by Richard Feynman.[2] Papp presented to an audience, including Feynman, an ill-fated demonstration in 1966, in which his engine exploded, killing one man and seriously injuring two others.[2] Feynman's conclusion was that Papp was a fraudster and the explosion an attempt by Papp to avoid discovery, although he notes that Caltech settled with Papp out of court.[3]

Feynman relented and gave up the plug. Papp put it back in the socket right away and the engine blew apart ... A Mattel engineer died"
