Mario Uggeri (1924-2004) attended the Art School in Cremona. When war broke out he became an Italian partisan. In 1943 he was caught and sent to Dachau concentration camp. His first published work ‘Rage l’invisibile’ appeared in the magazine Il Romanzo dei Regazzi in 1946. By 1949, Uggeri focused on the western genre, starting with ‘Rocky Rider’ in Intrepido, and later ‘Red Carson’ and ‘Yuma Kid’ for Bonelli. In 1954 Uggeri also started working for the English market. In 1957, he moved to London, where he worked for the Daily Mirror and the Sunday Express. Uggeri returned to Italy in early 1960. Among others he depicted ‘Bonanza’, ‘Rin-Tin-Tin’, ‘Geronimo’, ‘Ribot- il cavallo miliardo’ and ‘Smith & Wesson’.
