Henri Michaux (miʃo; 24 May 1899 – 19 October 1984) was a highly idiosyncratic Belgian-born poet, writer, and painter who wrote in French. He later took French citizenship. Michaux is best known for his esoteric books written in a highly accessible style. His body of work includes poetry, travelogues, and art criticism. Michaux travelled widely, tried his hand at several careers, and experimented with psychedelic drugs, especially LSD and mescaline, which resulted in two of his most intriguing works, Miserable Miracle and The Major Ordeals of the Mind and the Countless Minor Ones.
