Born in Århus, Ib Steinaa drew the children's comic 'Lise & Lasse', created by Henning Dahl-Mikkelsen, from 1946 to 1950. He also ghosted for Mik's 'Ferd'nand' strip. In the early 1980s, he did artwork on some Donald Duck stories for Egmont. Although he has some credits as a comics creator, he was mainly active in animation. He cooperated on two 'Ferd'nand' shorts in 1944, assisted on the feature Fyrtøjet/The Tinderbox and worked on several short commercial and educational films between 1944 and 1957. He was art director of Nordisk Tegnefilm (1957-65) and head of his own studios, Ib Steinaa Film (1965-67).
