The beginning of the product that Braun is most known for today: the electric shaver. The S 50 was the first electric shaver from Braun. The shaver was designed in 1938, but World War II delayed its introduction until 1951. It featured an oscillating cutter block with a very thin, yet very stable steel-foil mounted above it. This principle is still used in Braun's shavers of today.
The 1950s also saw the start of kitchen appliances, like the mixer MX 3 and the kitchen machine (Küchenmaschine or kitchen machine) Braun KM 3. The KM 3 is a family of food processors which started with the model KM 3/31 in 1957. Designed by Gerd Alfred Müller, these machines where built in nearly unchanged form for 36 years, until 1993.
In 1962, Braun became Braun AG, a publicly traded company. In 1963, the company started distributing microphones by U.S. manufacturer Shure in Germany. Also during the 1960s, Braun created the Rams-designed T3 pocket radio. By this time, Braun's film slide projectors were featuring high-quality optics and all-metal construction combined with sleek functionalist styling, and competed with higher-end Eastman Kodak and Leitz products in the global market.
