Philippe Delzenne began his career as a comic artist in 1977, working for Frank Sels on the series 'Zilverpijl'. Two years later he was hired by Jef Nys to assist on the adventures of 'Jommeke'. Delzenne left Nys in the mid 1980s to join Studio Peyo. For a period of ten years, he drew 'Smurfs' for all sorts of projects, and he has also cooperated with Peyo and Thierry Culliford on scripts.
Delzenne returned to Studio Jef Nys in 1998 and has cooperated on the 'Jommeke' stories together with Gerd van Loock since then. When Nys died in 2009, Delzenne and Van Loock became the official authors of the series. They alternatively write and draw their own 'Jommeke' albums, by now with credits.
