In 1938, Albert Hofmann, a Swiss chemist working at Sandoz Laboratories in Basel, successfully synthesized lysergic acid diethylamide, better known as LSD, from ergotamine. This compound was derived from ergot, a fungus known to cause hallucinations, which had been studied for its medicinal properties for centuries. Hofmann's work was part of a broader investigation into the chemical properties of ergot derivatives, aimed at finding potential therapeutic applications. The synthesis process revealed LSD, a powerful hallucinogen that would later capture the attention of scientists, artists, and counterculture movements alike.

As Hofmann continued his research in the following years, he later discovered the psychoactive effects of LSD when he accidentally absorbed a minute quantity of the substance through his fingertips in 1943. This incident prompted him to conduct further experiments, leading to the first intentional ingestion of LSD. Hofmann’s explorations revealed LSD’s potential as a tool for psychological exploration and therapy, igniting interest in its use in psychiatry and psychotherapy during the mid-20th century. The compound was eventually commercialized by Sandoz, leading to widespread use and experimentation in various fields.

Hofmann’s discovery sits at the intersection of science and culture, giving rise to a new era of psychedelic research, recreational use, and cultural significance in the 1960s. Over the decades, LSD became emblematic of the counterculture movement, influencing art, music, and social views on consciousness. This transformational compound has led scientists, philosophers, and the general public to delve deeper into the human psyche, exploring the boundaries of perception and reality.
