Raymond De Belser (17 June 1929 – 3 October 2014), pseudonym Ward Ruyslinck, was a Belgian writer. He is the son of Leo De Belser and Germaine Nauwelaers. His father was a librarian at an oil company, and Ward Ruyslinck grew up in a Roman Catholic family. During the Second World War, the family moved to Mortsel.
Ruyslinck was born in Berchem. At age 12, he had written a novel, Vaargeulen (in English, Channels). His father, who himself wrote the novel Gepantserde Beschaving (Armoured Civilization), sent his son's novel to Stijn Streuvels, who returned the novel unread but with an accompanying letter full of recommendations. The manuscript was lost during an air raid in 1943, which devastated their house. He wrote a number of poems and stories, some of which were published in the daily Het Vlaamsche land.
