Is any kind of compression at all used in audio CD's? I know that there is on DVD's, just at a huge bitrate.

Sony and Philips developed the CD, but the "blueprint" for encoding audio digitally at 44.1KHz was developed in the 1920's or 30's, by a guy who died a few months ago. Can anyone remember his name? I remember the newspapers crediting him as one of the founders of the "digital revolution".
The only person I can think of would be Harry Nyquist. His work in the 20's was originally related to telegraph signals but became the basis of modern sampling theory. But I think he died many years ago. For someone to do work in the 20's and die now, they would have to have lived to 100.
