Born in Tunis in 1947, he spent his childhood and adolescence in Paris, where he studied art and tried his hand at sculpture and animation, as well as publishing some works in the magazine Pilote. In 1970 he moved to Sweden, where he worked for several Swedish comics, including the Swedish edition of Mad, sometimes under the pseudonyms Tideli or Nisseman.

In 1975, he began to draw episodes of The Phantom for the Scandinavian market, and then he returned to France in 1987. In the same year, he created The White Lama with a script by Alejandro Jodorowsky, a series inspired by a trip to Tibet with six albums published by Les Humanoïdes Asocies, the publishing house responsible for most of the production. With the same scriptwriter, he launched The Magical Twins for Le Journal de Mickey for a more youthful audience. Still with Jodorowsky, in 1990 he revisited the character he had created in Mexico in the 60s, Hannibal 5, and four years later the two authors began the Juan Solo saga, which would last for four albums.

In 1998, Bess produced his first solo album, Escondida, and the following year he illustrated the second volume of Aphrodite, an erotic story with texts by Pierre Louÿs, and with a first issue drawn by Milo Manara. In 2000, for Carabas, he created two albums of Leele et Krishna, a series written by his wife Layla and set in ancient India. In 2004, he shifted gears with the graphic novel Bobi, published by Casterman, a work with more humor than his previous creations. He has also produced solo works such as Pema Ling or Le Vampire de Benarès.

In recent years, he has reinterpreted great literary classics such as Dracula, Frankenstein or Notre-Dame de Paris through his spectacular art.
