Rudolf Petersson (17 June 1896 to 17 April 1970) was a Swedish comic creator and the father of one of the most popular 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.
