Braille Typewriter from 1958 and Adding Machine "Hamann Selecta" from 1931

In September 1983, one of our then colleagues drove to the West Berlin State Administration Office to take a close look at discarded typewriters and adding machines.

These machines had to make way for the newer electric typewriters or the latest personal computers.

He brought two special finds back with him:

The Braille Typewriter – important equipment for blind persons

The Braille typewriter "Picht Record M" had been used by a blind employee in the State Administration. On it, dictation could be typed in shorthand. The six adjacent buttons each correspond with a dot of the Braille code. With another special typewriter, the Braille text was subsequently transferred to writing for the sighted.

The "Picht Record M" was developed at the end of the 19th century by the teacher and later director of the Steglitz School for the Blind, Oskar Picht. With the help of such machines, it was possible for blind people to enter into office careers for the first time.

The "fastest adding machine in the world" in 1931

The adding machine "Hamann Selecta" had probably not been in use in the State Administration for a long time. It was developed in the 1930s by the Berlin computing machine designer Christel Hamann.

The machine is capable of four basic arithmetic operations and has two input keyboards, a results register, and a rotary counter.

Even though it was considered the "fastest adding machine in the world" in 1931, 30 years ago it had long been overtaken by pocket calculators.

The "Exhibits of the Month" in 2013 were all procured in 1983, the first year of the Deutsches Technikmuseum. We are showing with this the spectrum of our early collections.
