Josef Allen Hynek (May 1, 1910 - April 27, 1986) was a U.S. astronomer, professor, and ufologist. He is probably best remembered for his UFO research: Hynek acted as scientific advisor to three consecutive UFO studies undertaken by the U.S. Air Force: Project Sign (1947-1949), Project Grudge (1949-1952), and finally, Project Blue Book (1952 to 1969); for decades afterwards, he conducted his own independent UFO research.
