He became a master of the short biographical story, depicting the lives of historic personalities, such as Caesar, El Cid, Marco Polo, Lincoln, Beethoven, Stendhal and Richard the Lionheart. These stories were collected in three albums at the publishing house Oberon.

He became the lay-out man of the Dutch Donald Duck weekly in 1969, and he kept this occupation until his retirement. Besides doing the lay-outs, he painted several illustrations for the magazine's text stories, as well as special editorial sections as 'Galerij der Groten, Klassiekers uit de Duckstadse Bibliotheek' and 'Terug in de Tijd met Mickey'. In the 1970s, he cooperated on the alternative magazine De Vrije Balloen. Balm made a comics adaptation of Charles Dickens' 'Barnaby Rudge' in 1988.

Together with his former studio colleagues Bert Bus and Nico van Dam, he was awarded the Bulletje & Boonestaakschaal for their contributions to the Dutch comics field in 2004.
