Harold E. "Hal" Puthoff (born 20 June 1936) is an American electrical engineer and parapsychology researcher. He co-led the U.S. government-funded remote-viewing research at SRI International from the 1970s, has proposed controversial theories linking inertia and gravity to the quantum vacuum, and co-founded the UFO company To The Stars Academy of Arts and Science in 2017.[1]

Education and early career

Puthoff was born in Chicago. He earned bachelor's and master's degrees in electrical engineering from the University of Florida and a PhD in electrical engineering from Stanford University in 1967, with a thesis on using the stimulated Raman effect as a tunable laser. He worked on tunable lasers and electron-beam devices and co-wrote the textbook Fundamentals of Quantum Electronics (1969) with his adviser, Richard Pantell.[1][2] He has also been reported to have served with the Naval Security Group and the National Security Agency.[1]

In the late 1960s Puthoff became involved with the Church of Scientology, reaching an advanced level by 1971 and writing for its publications, before breaking with it in the late 1970s.[1]

Remote viewing at SRI

From the early 1970s Puthoff and physicist Russell Targ directed research at SRI (then Stanford Research Institute) into claimed psychic abilities, funded by the CIA and later the military, in the program eventually known as Stargate. They tested subjects including artist Ingo Swann, former police official Pat Price and performer Uri Geller, and in 1974 published a paper in Nature reporting positive results.[1][3] Psychologists David Marks and Richard Kammann later reported that they could not replicate the results and found cues in the experiment transcripts that could explain the hits, and critics including Martin Gardner and James Randi disputed the methods.[1]

Vacuum physics and EarthTech

In 1985 Puthoff founded the Institute for Advanced Studies at Austin, later operating as EarthTech International, to study energy generation and advanced propulsion. He published a 1989 paper in Physical Review A proposing that gravity is a force arising from zero-point fluctuations of the quantum vacuum, and in 1994, with Bernard Haisch and Alfonso Rueda, a paper proposing that inertia is a zero-point-field effect.[1][4][5] Physicists including Steve Carlip disputed the calculations.[1] In 2002 he proposed a "polarizable vacuum" approach to gravity, and in 1998 he received a patent for transmitting information through a modulated potential, which has since been used as a case study of examiners missing pseudoscience.[1]

Puthoff was involved with Robert Bigelow's research efforts and contributed to the Defense Intelligence Agency's AAWSAP program, which produced 38 technical reports on advanced physics, including several by EarthTech researchers.[6] In 2017 he co-founded To The Stars Academy with Tom DeLonge and former CIA officer Jim Semivan. He has said publicly that he believes non-human craft have been recovered, and he appears in the 2025 documentary The Age of Disclosure.[1][7] Jacques Vallée's journals record decades of conversations in which Puthoff discussed rumoured hidden programs.
