Albert Hofmann (born January 11, 1906) is a Swiss scientist best known for synthesizing LSD. Hofmann authored more than 100 scientific articles and has written a number of books, including LSD: My Problem Child. On January 11, 2006, Hofmann became a centenarian, and was the focus of an international symposium on LSD. Hofmann also became interested in the seeds of the Mexican morning glory species Rivea corymbosa, the seeds of which are called Ololiuhqui by the natives. He was surprised to find the active compound of Ololiuhqui, ergine (lysergic acid amide), to be closely related to LSD.
