Oral Histories Series: The Hidden Impact of Women Edition – June 28, 2026

This in-person interview features Maria Mangini of The Shulgin Foundation and Denis Berry, whose vital role in psychedelic preservation is almost completely unknown. This event will also be livestreamed.

Much of the record of psychedelic history has been erased, forgotten, or never formally recorded — clandestine out of necessity. As the president of Timothy Leary’s Futique Trust, Denis was responsible for a remarkable achievement in preserving the records of the adventures of the twentieth century. As we move toward the establishment of a similar archival resource of materials documenting the remarkable history of the Shulgin Farm, Denis’ story is particularly relevant.

This series of interviews focuses on capturing the history of the missing decades of underground practice and recognition of the mentors and elders who have carried this wisdom forward. This specific conversation invites those newer to the field, especially aspiring therapists, guides, researchers, and community leaders, to learn directly from those who shaped the movement’s foundations, especially the women. Together, we’ll reflect on what it means to actualize our revelations about interconnectedness—not only in theory, but in how we live, heal, and serve.

This conversation will include a Q&A portion at the end.
