Philip Morrison

Philip Morrison (1915-2005) was an American physicist of Austrian-Jewish descent, renowned for his contributions to nuclear physics and the scientific search for extraterrestrial intelligence (SETI). A key figure in the Manhattan Project, he later became a professor at MIT. In 1959, Morrison co-authored the seminal paper 'Searching for Interstellar Communications' with Giuseppe Cocconi in Nature, proposing that extraterrestrial civilizations could broadcast detectable radio signals in the microwave spectrum and outlining target frequencies and stars for astronomers to search. This work founded modern SETI, influencing projects at Arecibo and beyond. Morrison distanced SETI from UFOlogy to maintain scientific credibility, emphasizing rigorous methods over unverified sightings or government cover-up claims. No direct involvement in military UFO programs is documented; his legacy underscores the profound implications of extraterrestrial life: 'Either we’re alone or we’re not, and either boggles the mind.'
