Rudolf Petersson (17 June 1896 – 17 April 1970) was a Swedish comic creator and the father of one of the most popular[citation needed] Swedish comics of all time: 91:an.

Petersson performed national service at the I 16 regiment in Halmstad, Halland, between 1916 and 1918.

Mandel Karlsson, the protagonist of 91:an, is based on two people Petersson met during his national service at I 16 — a blond and ill-tempered Smålandian who was turned soft by accordion music, and a friendly, short haired person.

Several of the officers in 91:an are also based on real people Petersson met during his service.
