Born in Geneva on 3 April 1951, Ceppi was the great-great-great-grandson of the inventor Georges-Auguste Leschot [fr]. At the age of 16, he exhibited a stained glass window in Carouge. He attended the Centre de formation professionnelle arts de Genève [fr] and self-published a novel titled Le Guêpier about a traveller named Stéphane Clément.[2] In 1977, he published the first album in the series.[3] During the 1980s, he began publishing with Casterman, switching from his previous publisher, Les Humanoïdes Associés.[3] At the same time, he began publishing his illustrations in the magazine Métal hurlant.[4] He then published editions 4 through 7 of the Stéphane Clément series under the title Une Aventure de Stéphane from 1981 to 1985.[5]
Ceppi returned to Les Humanoïdes Associés in 1991 and wrote of Stéphane Clément travels to Cameroon, the Philippines, and Indonesia.[6] In 2009, the publisher released a full collection of his works in the original black and white.[7] After a hiatus, he returned to comics in 2017 with the one-shot Lady of Shalott, which told a story about the world of art in Geneva. This edition brought Stéphane Clément together with others in CH Confidentiel.[8]
Ceppi died on 4 November 2024, at the age of 73.[9]
