Hal Puthoff

Harold E. "Hal" Puthoff (born 1936) is an American physicist whose career connects the government's psychic-research era to the modern UAP establishment. He co-founded the Stanford Research Institute's remote-viewing program, directs the Institute for Advanced Studies at Austin, and was a founding member of To The Stars Academy.

Puthoff earned his doctorate at Stanford and co-authored a standard quantum electronics textbook. From 1972 he and Russell Targ ran the CIA- and DIA-funded remote-viewing research at SRI that became Star Gate lore, working with subjects including Ingo Swann and Uri Geller. His later physics focused on zero-point energy and spacetime engineering concepts.

Puthoff was a NIDS science board member, an AAWSAP-era contributor (his institute helped manage the Defense Intelligence Reference Documents), and TTSA's vice president for science, where he oversaw the ADAM materials project analyzing alleged UAP artifacts. He briefed government audiences during the AATIP era, spoke publicly after 2017 about materials with reported anomalous isotope ratios, and co-founded the Sol Foundation's orbit of academically minded UAP research. Few living figures appear in more chapters of the story.

Puthoff has claimed that some analyzed materials show engineering-like isotopic anomalies without terrestrial explanation, couched carefully, and that the phenomenon is real and worth physics' attention. His contribution is continuity and respectability across programs, plus a paper trail of DIRDs and briefings that PURSUE-era releases keep surfacing.

Skeptics note the remote-viewing program's scientific collapse under external review (the 1995 AIR evaluation), Geller-era methodological criticisms, and that no anomalous-materials claim has reached peer-reviewed publication with public samples. Critics also fault his early Scientology involvement (which he publicly renounced decades ago) as pattern evidence of credulity. Supporters answer that his classified-world credibility is why officials kept funding him, and that quiet materials work cannot publish freely.

Puthoff, in his late 80s as of 2026, continues at his Austin institute and remains a touchstone advisor to the field's scientific wing.
