Born in Vienna de Majo studied at the Vienna Commercial Academy in preparation for a career in the family textile business. However, he opted for a freelance career in graphic design, establishing a studio in Belgrade in 1936. In 1939 he emigrated to Britain, where he worked as a broadcaster with the BBC Overseas Service before serving as a pilot with the Royal Yugoslav Air Force during the Second World War. In 1946 he established W. M. de Mayo and Associates, specializing in graphic design and exhibition work, gaining a wide range of commissions that ranged from the highly detailed series of Letts diaries to the large‐scale Farm and Factory Exhibit, Ulster, for the 1951 Festival of Britain. In 1963 he became the founder president of the International Council of Graphic Design Associations (ICOGRADA) which has represented since then the interests of the graphic design profession in over 60 countries. His role as a speaker at many international design conferences and as chair of many important design committees established him as an important voice, a position that was recognized by the Society of Industrial Artists and Designers (See Chartered Society of Designers), which awarded him its Design Medal in 1969.
