Real name: né Julian Hallett (James Williamson)

British writer, editor, translator and controversial entrepreneur (b. 1959, Plymouth, England); likely based in Bangkok, Thailand, since the mid-2000s. Julian Hallett (who legally changed his name in honor of The Stooges guitarist James Williamson) is best known as the founder of independent publisher Creation Books and several other associated imprints, including a short-lived Cosmodelic Records label. As a fictional writer, he specialized in erotica, esoteric horror and other extreme topics, publishing under various pen names, mostly James Havoc. Williamson co-edited Ultra-gash Inferno: Erotic-grotesque Manga (2001), one of the very few anthologies of the notorious manga artist Suehiro Maruo published outside of Japan, and translated Marquis de Sade's 120 Days of Sodom for his imprint. In January 2012, a group of former authors came out with the CreationBooksFraud.com website, accusing James Williamson of criminal fraud and multiple other misdoings.

Julian Hallett lived in Plymouth until the early 1980s, working at the local record store Meat Whiplash. Before changing his name to Williamson, he was also known as "Ferd" or "Ferdy," "Julian Halibut," and generally liked to use pseudonyms. After briefly living in London, James/Julian settled in Brighton in the mid-80s, where he operated a small book mailorder advertised in New Musical Express and other British musical press. Williamson befriended members of Primal Scream band, with the band's lead singer, Bobby Gillespie, starring in his underground Super-8 "lo-fi" short film Crimes Against Pussycat (1989) about XV-century French child murderer Gilles de Rais. James soon met Alan McGee, the founder of renowned Creation Records, through them. The same year, Creation Records released an eponymous debut album by Williamson's short-lived industrial/avant/goth band Church of Raism. An accompanying novel, Raism, written under James Havoc's name, came out on the label's newly-launched publishing branch, "Creation Press," with James as editor-in-chief. The venture soon went independent, rebranding to Creation Books. In his autobiography almost 25 years later, Alan McGee described Williamson as "an entirely diabolical human being [with whom they] had great fun at the time."

In the early 2000s, James Williamson relocated to New York City. Since then, according to CreationBooksFraud.com, he has begun fraudulent activities, managing the entire operation remotely online under the facade of a legitimate business with staff in the UK and the US. He supposedly used multiple aliases to pose as various employees, including the company's lawyer, "John Bundrick," with the.rabbit@creationbooks.com email (a clear nod to an iconic keyboardist John "Rabbit" Bundrick, and rather hilarious in light of Williamson's name change in the past). The website outlined numerous further allegations, including printing books on unpaid credit, withholding royalties, and illegally selling translation rights without the knowledge or consent of original authors. French writer Agnès Pierron also accused Williamson of plagiarizing her writing, publishing two texts and 25 original illustrations as Chapel Of Gore & Psychosis: The Grand Guignol Theatre under the "Jack Hunter" pen name.
