Claudio Naranjo, M.D. (1932-2019), was a well-known psychiatrist, philosopher, professor, and university researcher from Chile. He was a Fulbright scholar at Harvard, a Guggenheim fellow at Berkeley, a council member of the Education Policy Research Center at the Stanford Research Institute, and a professor at UC Santa Cruz, the California Institute of Integral Studies. He was a pioneer in the use of psychedelics for psychotherapy and was known for his long collaboration with Alexander “Sasha” Shulgin. The author of many articles, papers, and books, his legacy lives on through the Claudio Naranjo Foundation (Fundación Claudio Naranjo).

"Claudio Naranjo was a profound inspiration to me and to so many others. Claudio helped train MAPS' first therapist team for MDMA-assisted psychotherapy for PTSD, for our study in Spain that began in 2000. Claudio's talk was the highlight of the recent World Ayahuasca Conference. Despite his health challenges, in his final days he indicated an interest in being involved in MAPS' psychedelic reconciliation project focused on Israelis and Palestinians who are taking ayahuasca and sometimes MDMA together. We honor Claudio's memory by continuing to work to develop MDMA and other psychedelics into prescription medicines, and beyond."
