Stanislav Grof (born July 1, 1931) is a Czech psychiatrist, one of the founders of the transpersonal psychology and a researcher in the field of consciousness studies.
Grof is known, in the scientific circles, for his early studies of LSD and its effects on the psyche – psychedelic therapy. Grof constructed a theoretical framework for prenatal, perinatal and transpersonal psychology in which LSD and other powerfully emotional experiences were mapped onto a person’s early fetal and neonatal experiences. Following the suppression of legal LSD use in the late 1960s, Grof develops a theory that many states of mind could be explored without drugs by using certain breathing techniques. He continues this work under the trademark “Holotropic Breathwork”.
Grof received the VISION 97 award granted by the Foundation of Dagmar and Václav Havel in Prague on October 5, 2007.
Grof is a prolific author, having written numerous books about LSD’s use in psychotherapy, altered states of consciousness, and other methods of conducting deep psycho-spiritual work.

Leo J. Zeff
Leo Zeff (May 14, 1912 – April 13, 1988) was an American psychologist and pioneer psychotherapist from Oakland, California who used LSD, MDMA, and other psychoactive drugs in psychotherapy in the 1970s.
Leo Zeff was introduced to LSD in 1961 when he was working as a Jungian therapist, and he developed a method for administering LSD to patients during psychotherapy. Eventually, he discovered how effective psychedelics could be in helping heal his patients.
In 1977, when Alexander Shulgin introduced Zeff to MDMA, the drug was still legal. After trying MDMA, he abandoned his retirement plans and traveled across the country introducing MDMA to other therapists. Zeff popularized it in the psychotherapeutic community, dubbing it “Adam” because he believed it returned one to a state of primordial innocence.
Zeff is the author of the books: The Secret Chief: Conversations with a Pioneer of the Underground Psychedelic Therapy Movement, MAPS (1997); The Secret Chief Revealed: Conversations with Leo Zeff, Pioneer in the Underground Psychedelic Therapy Movement, MAPS (2004).
