No. Charles picked up after T.A. retired in 1927, leaving him head of the
company in that year. Both Charles and Theodore went to MIT with Theodore
having a penchant for mathematical physics and was secretly pursuing
electrical recording and playback in a separate laboratory set up for him.
It was during this time that electrical recording 'finally' got into gear.
It is Theodore we have to thank for the marvelous C-1 and C-2 phonographs.
The pick-up is absolutely ingenious and the phonographs have a wonderful
sound, especially playing the 52000 series. Unfortunately, they came too
late. They were brought out late in 1928 and were the last phonographs made
by the company. Very few C-1s are known. Only a few dozen C-2s are known to
exist, of which I am a proud owner and can attest to their usual Edison
quality.
btw...the L.P. cylinder Edison made in 1899 had 450 grooves per inch.
Obviously, it wasn't practical at that time either for even more reasons,
one being a suitable material for pressing. Still, that's when the L.P. work
began and was first achieved. As far as Theodore goes, I bow to him for the
electronic phonographs and that ingenious pick-up with the offset diamond
stylus.
