Timothy Leary is considered by many to be one of the most prominent figures of the 60's counter culture, and whose legacy has had a lasting impact on modern pop culture, literature, television, film and, especially, music.

Leary is perhaps best known for his advocacy of psychedelic drugs as a means of personal growth and increased cognitive awareness, advocating for people to "turn on, tune in, and drop out."

After being introduced to psilocybin mushrooms on a trip to Mexico in 1960, an experience that drastically altered the course of his life, Leary embarked on a mission to expand human consciousness, through the use of psychedelic drugs.

Upon his return to the U.S., he began a research program known as the Harvard Psilocybin Project, analyzing the effects of psilocybin on humans, with the ultimate goal of assisting people in gaining a higher level of consciousness.
