Bob De Groot is a Belgian comics writer, best known for his collaborations with Turk on the series 'Robin Dubois', 'Léonard' and 'Clifton'. However, he began his career as an artist. Born in Brussels, he was seventeen years old when he enrolled in art school. During this period, he met Maurice Tillieux, whom he assisted on 'Félix', and who became a major influence on De Groot. In the following years, De Groot produced up to 300 pages for weekly newspaper supplements, as well as short stories for Pilote in from scripts by Hubuc, Reiser and Fred. It was with Fred that he created the funny espionage serial 'L'Agent Caméléon 4 x 8 = 32'. They were joined by the artist Turk to assist on the graphical part of the series.
By 1975, the duo created 'Léonard', their longest running series and a spoof on Leonardo da Vince. It was first published in Achille Talon Magazine and also gained a lot of popularity in the Netherlands through its publication in Eppo magazine. Books have been published subsequently by Dargaud, Appro and Le Lombard since 1977.
