Career and Professional Life

The Fitz Hugh Ludlow Memorial Library, the greatest collection of drug-related literature in the world, was founded by him and his wife. Currently, he is the proprietor of Flashback Books, a mail-order bookstore that specializes in out-of-print, rare, and uncommon books, magazines, and related printed materials on the culture, literature, and science of psychoactive substances.

A biopic about Leary is being planned by Horowitz and actor Leonardo DiCaprio, and it will be scripted by Craig Lucas. The Fitz Hugh Ludlow Memorial Library is a library of psychoactive drug-related literature founded in 1970 by Michael D. Horowitz, William Dailey, Cynthia Palmer, and Robert Barker, who merged their private libraries.

It was named after Fitz Hugh Ludlow, author of The Hasheesh Eater, the first full-length work of drug literature written by an American (1857). It was the world’s largest library, and it was based in San Francisco, California. In 2003, the Ludlow Library merged with the Ludlow Santo Domingo Library in Geneva, Switzerland.


Following the death of its owner, Julio Mario Santo Domingo, Jr., his family loaned the book collection to Harvard University’s Houghton Library and the music collection to Cleveland, Ohio’s Rock and Roll Hall of Fame and Museum.

The library expanded rapidly during the 1970s and operated out of San Francisco as an international resource for psychoactive drug research and the study of psychoactive drug use in contemporary and historical societies.

The Ludlow Library thrived during one of the most intense periods of media interest in the personal, social, scientific, and political aspects of the drug experience. Hundreds of writers, filmmakers, and news media researchers used the Library to gather accurate historical information on cannabis, opiates, coca and cocaine, and psychedelics for their publications.
