Dieter Rams was a leading designer of industrial products at Braun from 1955 to 1995, and his designs made the Braun name synonymous with good design, summed up in his famous ten principles of good design. One is well expressed in this calculator: “Good design makes a product understandable.”

All the numerals are clearly indicated in convex white-on-black buttons, function buttons are in white symbols on brown, and the equal sign—perhaps the most-used function key—is black on a yellow button. This model ET 22, designed by Rams with Dietrich Lubs, is the second calculator in a series that began in 1975.
