To celebrate Bicycle Day on April 19th, the date of Albert Hofmann’s — and the world’s first LSD trip in 1943, we are publishing this excerpt from the forthcoming interview with Michael Horowitz — the third installment of the Acid Bodhisattva series, coming soon to Timothy Leary Archives.

Images: from Lysergic World (April, 1993): Albert Hofmann in 1977 (above), and the route of his famous bicycle ride on LSD through Basel, Switzerland on April 19, 1943, from Sandoz Laboratories to his house.
