I knew Theodore had worked at the Lab since he graduated in 1923, so it seemed unlikely that he'd have nothing to do with the LP work. I know I've read in more than one place about his LP work, but have had trouble remembering where.
. Here's one quote, from Lee Munsick: "Ask me sometime about the problems Theodore Edison told me he had in the development of the Edison Long Playing machine and recordings." . Lee also calls Theodore the "project supervisor" for the LP. ----- Original Message ----- From: "Bruce Mercer" <maxbu...@sigecom.net> To: <phono-l@oldcrank.org> Sent: Wednesday, May 03, 2006 4:08 PM Subject: [Phono-L] Theodore Edison > > ----- Original Message ----- > From: "Bruce Mercer" <maxbu...@sigecom.net> > To: <phono-l@oldcrank.org> > Sent: Wednesday, May 03, 2006 3:05 PM > Subject: Re: Phono-L Digest, Vol 3, Issue 109 > > >> >> >> >>> ---------------------------------------------------------------------- >>> >>> Message: 1 >>> Date: Tue, 02 May 2006 15:02:00 -0400 >>> From: "Dan Kj" <ediso...@verizon.net> >>> Subject: Re: [Phono-L] The Practical Long Play Record >>> To: "Antique Phonograph List" <phono-l@oldcrank.org> >>> Message-ID: <004a01c66e1a$e7120240$6600a...@new> >>> Content-Type: text/plain; format=flowed; charset=iso-8859-1; >>> reply-type=original >>> >>> So, did Theodore work on the Edison LP at all ? >> >> No. Charles picked up after T.A. retired in 1927, leaving him head of the >> company in that year.
