Paris-born Didier Teste, better known as Dieter, had no intentions of becoming a comics writer until he met Jean Léturgie. Dieter wrote his first stories for artists like Bruno Bouteville, Marc Malès and Thierry Robin, that were mainly published in Triolo in 1985 and 1986. In the following year, he began a fruitful collaboration with the publishing houses Milan and Bayard Presse. He wrote a great many stories and adaptations for magazines like Diabolo, Mikado, Astrapi, Okapi, Je Bouquine and I Love English, that were drawn by Olivier TaDuc, Christian Rossi, Dominique Rousseau, Raymond Poïvet and Pierre Frisano. His first long story was 'La Déesse aux Yeux de Jade', created with Michel Plessix and published by Milan in 1987.
Dieter and Plessix created 'Les Aventures de Julien Boisvert' for Delcourt in 1989. This critically acclaimed series ended after four episodes in 1995, when the authors decided the psychological development of their globetrotting adventurer was concluded. 'Julien Boisvert' set the tone for Dieter's further work - human stories with a strong emphasis on character development.

In addition, he created the adventure series 'Sark' with TaDuc (Glénat, 1991) and the graphic novel series 'Névé' with Emmanuel Lepage (Glénat, 1991-1997). He wrote the sole episode of the series 'Le Griffon' for Michel Durand and the publishing house Alpen in 1992. He co-wrote the fantasy series 'Labyrinthes' with Serge Le Tendre for artist Jean-Denis Pendanx (Glénat, 1993-1997). He also teamed up with Florenci Clavé to create 'Voyages en Amertume' for Vents d'Ouest between 1992 and 1994.
With Emmanuel Moynot, Dieter created comics like 'Le Temps des Bombes' (Dargaud, 1992-1994), 'Qu'elle Crève la Charogne' (Vents d'Ouest, 1995), the diptych 'Nord-Sud' (Dargaud, 1997), 'Vieux fou!' (Delcourt, 1999-2001) and 'Monsieur Khol' (Glénat, 2001). He also cooperated with Viviane Nicaise on adventure and detective comics like 'Loranne' (Glénat, 1998-2000), '6 Jours et Mourir' (Glénat, 2001) and 'Le Vie en Rose' (Glénat, 2003-2004).
He expanded his collaborations and worked with Éric Hérenguel on 'Edward John Trelawnay' (Delcourt, 1997-1999), Xavier Fourquemin on 'Alban' (Le Téméraire/Soleil, 1998-2004), Stéphane Duval on 'Janet Jones photographe' (Delcourt, 1999-2001) and Guillaume Sorel on 'Typhaon' (Casterman, 2000-2001).
He turned to science-fiction for the series 'Amenophis IV', that was drawn by Étienne Le Roux for Delcourt between 2000 and 2003. Other new creations were the fantasy series 'Anges' in cooperation with Olivier Boiscommun (Les Humanoïdes Associés, 2001-2005) and the funny western 'Outlaw' with Xavier Fourquemin (Glénat, 2001-2005).
Dieter lives and works in the Britton town of Thorigné-Fouillard. He adapted local tales to comics in the book 'L'Ankou', with art by Stéphane Hearteau in 2004. He returned to children's comics with the series 'Jane des Dragons', that was drawn by Boris Guilloteau for Delcourt Jeunesse from 2005 to 2007.
