Eduard De Rop attended the Antwerp art academy, and took evening courses from the academy of Berchem. He began his career designing furniture, but eventually pursued a career as an advertising artist. He produced many movie posters for the Nelissen agency, and he made some illustrations for the magazines Bolero and Mascotte under the pseudonym Pim. In addition, he did color illustrations for Piccolo. For the advertising agency Hopstaken, he drew the advertising strip 'De Vrolijke Lotgevallen van Hans Snugger en Kwikzilver', that appeared in Gazet van Antwerpen in 1959.
De Rop additionally made the comic 'De Zwarte Boeddha' for the weekly Ons Land in 1958, and contributed the comics 'Clara Detective' (1959), 'Stan Stikker tegen de Raaf' (1959) and 'De Familie Zwanzers' (1960) to the women's magazine Iris under the pseudonym Drope. He drew the gag strip 'Geschipper naast Mathilde', based on the Flemish tv show, in cooperation with E. Decamps in Zondagmorgen from 1960. In the same magazine, De Rop and Decamps came up with 'De Blaffende Stopnaald' under the collective pseudonym Ro-Cam in 1962.
Eduard De Rop was one of Willy Vandersteen's longtime assistants, and has worked on nearly all of the master's series.
