In 1971 Bruno Ninaber van Eyben graduated cum laude from the College of Art in Maastricht as a jewellery designer. In the 1970s he designed a bracelet watch (1973), a pendant watch (1976), and a fluorescent lighting system (1977). In 1979 he received the Kho Liang Ie Award, a Dutch award for industrial design.
In 1980 he designed the last series of Dutch guilder coins, which were in circulation from 1982 until the introduction of the euro in 2002. In 1997 he started his own studio called Bruno Ninaber van Eyben design+production in Delft. In May 1998 he won the contest for the design of the reverse side of the Dutch euro coins.
