Timothy Leary (1920--1996) was a world-renowned psychologist, a West Point student, a defrocked Harvard professor, a relentless champion of brain-change, a stand-up philosopher, a Federal "criminal" and a counterculture guru. His charisma and radically humorous nature often captured the attention of the world. Some called him "the most dangerous man on the planet." Leary continues to be an inspiration for millions of freedom-loving and free-thinking people throughout the world.
