I did a high school exchange year in Delft in 1995 and my host family had Boes on tape, I didn't understand half the Dutch but that cow's voice I understood fine. Just found out tonight. Sorry for a stranger grieving something so far from home.

Guido Jonckers was a Dutch actor, voice actor, theatre director and drama teacher from The Hague. Television audiences knew him as Pa in the schools series Verburgh met een H, as the man in the yellow jumper in the Moulinex advertisements and, for a generation of children in the late 1980s, as the deep brown voice of the ox Boes in the cartoon series of the same name.
Born in The Hague on 24 October 1947, he worked for more than forty years in professional theatre, on television and behind the microphone. He acted and directed with the Haagse Comedie, where he also sat on the artistic council, was resident director of the musical Les Miserables, played for John Lanting's Theater van de Lach and taught drama students at the Hogeschool Rotterdam. He was regarded as an authority on Anton Chekhov and directed productions of The Three Sisters, The Cherry Orchard, The Seagull, Uncle Vanya, The Proposal and The Jubilee.
On screen he had roles in Baantjer, Goudkust and Flodder, guest parts in Goede tijden, slechte tijden, SamSam and Kinderen geen bezwaar, and presented the darts quiz Bullseye. He fronted language courses and travel programmes for Teleac, and as a voice actor he worked on Alfred J. Kwak, Kleine Nemo and De Seend as well as Boes.
Alongside his professional career he spent decades working with amateur companies. From 1978 he directed the Schiedam theatre society Utile Dulci, and for the Delft company de Flits he adapted Aristophanes. Each summer he staged the Jorisproductie, an open air performance in the park of the mental health organisation GGZ Delfland, with local players and sets, costumes and props made by GGZ clients. His free adaptations of Shakespeare, Gogol, Aristophanes and Buchner were made to entertain children while carrying a second layer for adults, and he opened every performance with a welcome of his own.
In later life he spoke publicly about a hereditary condition that had taken his hearing and his sense of balance, and about the aids that let him keep directing. He began work on a new production in 2026 until illness forced him to stop. He died on the evening of 25 October 2026, shortly after his 79th birthday, and the theatre community of Delft, Schiedam and The Hague mourned a craftsman who never ranked professional stages above amateur ones.
