Terence McKenna, author and explorer, traveled the world to work and live with shamans. He added to their shared knowledge of rituals his own efforts to preserve the plants used in these ceremonies. Co-author of The Invisible Landscape and Psilocybin: The Magic Mushroom Grower's Guide, Terence mesmerized his many lecture audiences with tales of science and shamanism. He was co-manager of a botanical garden in Hawaii for endangered tropical plants. He died in 2000.
