Hans Hilfiker

Hans Hilfiker (15 September 1901 – 2 March 1993) was a Swiss engineer and designer. In 1944, working for the Swiss Federal Railways, he designed the Swiss railway clock, which became an international icon. The SBB clock was not Hilfiker's only contribution to modern living. He developed the concept of the fitted kitchen and was responsible for the standard Swiss dimensions for kitchen components (55/60/90 cm).
