Johannes van de Weert was a cartoonist active in the Rotterdam punk and squatter's movements of the 1980s. He was a singer with the punkband De Rondos and he started self-publishing small comic booklets in the late 1970s. After the booklets 'Geis', 'Geis gaat op reis' and 'Hamer en Sikkelstrip' he created his character 'Redrat' for the fanzine Raket in 1980. The character soon became an icon for the squatter's movement and even the stories were even translated in German.
Van de Weert made his final 'Redrat' booklet in 1983, when the punk movement came to an end. He then focused on other comics, such as 'Uitverkoop' (1984) about the NSB and 'No Pasaran' (1986) about a Dutchman during the Spanish civil war. When De Rondos released a compilation box in 2009, Van de Weert made a new 'Red Rat' retrospect comic for the occasion, published by Papieren Tijger. Van de Weert now works as a fine artist in Amsterdam.
