Gunnar Persson is the son of Elov Persson, the creator of the classic Swedish comic characters 'Kronblom' and 'Agust'. Born in Storvik, he showed an early artistic talent, and attended the Bergh school in Stockholm between 1952 and 1954. He then went to work as a freelance newspaper artist in Stockholm. He worked for DN and Stockholmstidningen and developed a speciality in cartooning, what he did for several papers from the late 1950s.
In 1961 he created his first comic strip, the pantomime series 'Gus', that appeared in about 30 newspapers throughout Sweden, Norway and Finland. He joined 91:an in 1965 and first created 'Herr Larsson' for this comic magazine. In 1967 he took over his father's comic 'Kronblom', and he has continued it for over forty years, not only in 91:an, but also in Allers.
Persson additionally worked on the title comic '91:an', working as the assistant of Nils Egerbrandt from 1969, and as a writer on 'Flygsoldat 113 Bom'. Persson also created the comic 'Klackamo Dagbok', that appeared in the magazine until 2000.
