Ribbon trivia

[clintrubber]

I read this bit of trivia somewhere:

Physicist Walter H. Schottky did not invent the hot carrier diode that carries his name.
Rather, he is responsible for one of the most crucial developments in audio and radio history: the ribbon microphone.

As also confirmed by wikipedia :  http://en.wikipedia.org/wiki/Walter_H._Schottky#Inventions

In 1924, Schottky co-invented the ribbon microphone along with Gerwin Erlach. The idea was that a very fine ribbon suspended in a magnetic field could generate electric signals. This led also to the invention of the ribbon loudspeaker by using it in the reverse order, but it was not practical until high flux permanent magnets became available in the late 1930s.

In the early 1920s, Drs. Walter H. Schottky and Erwin Gerlach co-invented the first ribbon microphone.[4] By turning the ribbon circuit in the opposite direction, they also invented the first ribbon loudspeaker. A few years later, Dr. Harry F. Olson of RCA started developing ribbon microphones using field coils and permanent magnets.

Didn't knew that ;-)

FWIW....

that's a new one!
