John C. Lilly, M.D., an unparalleled scientific visionary and explorer, has made significant contributions to psychology, brain research, computer theory, medicine, ethics, delphinlogy, and interspecies communication.

His work launched the global interest in dolphins and whales, provided the basis for the movie Day of the Dolphin, and stimulated the enactment of the Marine Mammal Protection Act. Lilly's interest in the nature of human consciousness led him to invent the isolation tank in the 1950s. In the early sixties, Lilly encountered LSD and soon took his experiments with this mindchanger to the isolation tank. The hairraising experiences that resulted formed the essence of the movie Altered States.

Lilly's life and work at the forefronts of human knowledge encompass the major themes of the twentieth century. His dozen books have sold millions of copies worldwide. A distinguished brain researcher even before he became a public figure, Lilly has sown the seeds of several scientific revolutions, including the theory of internal realities, the hardware/software model of the human brain/ mind, and the initiation of worldwide efforts at interspecies communications with large-brained dolphins.

Devoted to a philosophical quest for the nature of reality, Lilly pursued a brilliant academic career among the scientific leaders of the day, mastering one science after another and eventually achieving a perspective that transcends the centuries-old conflict between rationality and mysticism. He has lived in the company of associates and intimates including Nobel physicists Richard Feynman and Robert Milliken, philosophers Buckminster Fuller, Aldous Huxley, and Alan Watts, psychotherapy pioneers R.D. Laing and Fritz Perls, spiritual teachers Oscar Ichazo and Baba Ram Dass, and a host of luminaries, inventors, writers, and Hollywood celebrities.

John Lilly was the twentieth century's foremost scientific pioneer of the inner and outer limits of human experience. He was a relentless adventurer whose "search for Reality" led him repeatedly to risk life and limb, but whose quests resulted in astonishing insights into what it means to be a human being in an ever more mysterious universe. John passed to the other side on September 30, 2001. We can only imagine what limits he is trancending now.
