Born in London in 1929, the industrial designer Kenneth Grange attended the Willesden School of Arts and Crafts there from 1944 until 1947. While serving in the Royal Engineers, Kenneth Grange took the opportunity of training in technical drawing. After leaving the armed forces, Kenneth Grange freelanced for several London architecture and design practices.
In 1958 Kenneth Grange founded a company: Kenneth Grange Design Ltd. He gradually came to specialize in product design, with Kodak and Kenwood, the electrical appliances maker his chief clients. In 1972 Kenneth Grange joined Alan Fletcher, Colin Forbes, and Mervyn Kurlansky in founding Pentagram, an interdisciplinary design practice that now has twenty partners and branches worldwide.
In 1960 Kenneth Grange designed the "Chef" line in food mixers for Kenwood. For Kodak Kenneth Grange designed the housing of the "Pocket Instamatic" camera in 1975 and, in 1979, the "Parker 25" fountain pen for Parker. For London Transport Kenneth Grange designed the Adshel busstops in 1990. In 2000 he gave the London taxis the facelift that has kept them up with the times. Since 1970 Kenneth Grange has also taken on commissions from Japanese firms and his work has exerted an enormous influence on Japanese product design.
Kenneth Grange views product design as an opportunity for innovation rather than merely as a means to aesthetic improvement, which is why he sees it as such an important part of the manufacturing process.
