Willem Hendrik Crouwel was born in 1928 in Groningen, Netherlands. He studied at the Academy of Arts and Crafts in Groningen and took evening classes at the Institute of Arts and Crafts, now the Rietveld Academy. His teacher, Charles Jongejans, was trained by notable Dutch designers Paul Schuitema and Gerard Kiljan. In 1952, Crouwel began his design career at Enderberg, designing exhibitions and trade stands, gaining valuable experience. After leaving Enderberg in 1956, he founded a studio with industrial designer Kho Liang Ie, working on various projects across design disciplines, including graphic and exhibition design. Influenced by mid-century Swiss typography, Crouwel explored letterforms and graphic systems, using fonts like Helvetica and Univers. His early clients included the Van Abbe Museum, where he designed catalogues and posters. In 1963, he co-founded the influential design agency Total Design and also started working for the Stedelijk Museum, collaborating with Edy de Wilde until 1986.
