One of the most amazing and controversial characters of the "psychedelic epic", Al Hubbard (1901-1982) was an inventor, a smuggler during Prohibition and a secret agent in Canada and USA and finally a millionaire.
During the mid- 1950s and 1960s, after experimenting with LSD (the first time in 1951) he became an ardent proselytizer of the awakening and spiritual properties of the psychedelic drugs. He introduced more than 6000 people to LSD - including politicians,scientists, artists and church figures. He is known as the Johnny Appleseed of LSD.
