Albert Hofmann, the Swiss chemist who discovered the hallucinogenic drug LSD, has died aged 102.
Born on January 11 1906, Hofmann discovered LSD - lysergic acid diethylamide, which later became the favoured drug of the 1960s counterculture - when a tiny quantity leaked on to his hand during a laboratory experiment in 1943.
He noted a "remarkable restlessness, combined with slight dizziness" that made him stop his work. "At home I lay down and sank into a not unpleasant intoxication-like condition, characterised by an extremely stimulated imagination," Hofmann wrote in his book LSD: My Problem Child.
"In a dreamlike state, with eyes closed (I found the daylight too unpleasantly glaring), I perceived an uninterrupted stream of fantastic pictures, extraordinary shapes with intense, kaleidoscopic play of colours. After some two hours this condition faded away."
A few days later, Hofmann intentionally took a dose of LSD and experienced the world's first "bad trip".
"On the way home, my condition began to assume threatening forms. Everything in my field of vision wavered and was distorted as if seen in a curved mirror," he said.
"My surroundings had now transformed themselves in more terrifying ways. A demon had invaded me, had taken possession of my body, mind, and soul. I jumped up and screamed, trying to free myself from him, but then sank down again and lay helpless on the sofa. The substance, with which I had wanted to experiment, had vanquished me."
