The Fitz Hugh Ludlow Memorial Library is a library of psychoactive drug-related literature created in 1970 by Michael D. Horowitz, Cynthia Palmer, William Dailey, and Robert Barker, who merged their private libraries. It was named for Fitz Hugh Ludlow, author of the first full-length work of drug literature written by an American, The Hasheesh Eater (1857). It was the largest such library in the world and was based in San Francisco, California. The Ludlow Library became part of the Ludlow Santo Domingo Library in Geneva, Switzerland, in 2003. After the death of its owner, Julio Mario Santo Domingo, Jr., his family loaned the book collection to the Houghton Library at Harvard University and the music collection to the Rock and Roll Hall of Fame and Museum in Cleveland, Ohio.
