Jaap Veenendaal was born Evert Jacob Veenendaal in Amsersfoort as the son of a book salesman. He developed an early talent for drawing, and was later a pupil of Johan Herman Isings in Soest. Veenendaal went to work as a painter and illustrator, and also as a drawing teacher.
Veenendaal has worked as an illustrator for publishers like Ploegsma, Ten Brink, Huisman, Callenbach, Bosch & Keuning, Edecea, Van Goor, Kluitman and Noordhoff. This includes drawings for books by W.G. van der Hulst, P.A. de Rover, A. Grimme, Klaas van der Geest and Cor Bruijn.
In the 1930s, he made nature drawings for the the 'Kwispelstaart' section of children's magazine De Merel. Among his more notable work were his drawings for the school booklet series 'Open Vensters' in the 1940s. He also spent about a year in Bandung for an Indonesias version. He also made two picture books for Kanis & Gunnik coffee with biologist Rinke Tolman.
He painted many oilpaint portraits during World War II, as well as city views of Amersfoort. Veenendaal's many drawings of Amersfoort were issued as postcards after the war. In the 1950s and early 1960s he also established himself as a comic artist under the signature Javé. He drew two stories with the adventures of the little pygmy boy 'Bongo', the first containing 124 strips, the second 541. These stories were published in a couple of Dutch newspapers, including most likely Trouw. Jaap Veenendaal passed away in Soest in 1981.
