Head of the U.S. Air Force's investigation into unidentified flying objects from 1951 to 1953. Upon taking charge of Project Blue Book in 1952, he insisted upon the use of the term "unidentified flying object" instead of "flying saucer" and introduced more rigorous procedures for reporting and analyzing information on sightings.
