[78-L] Am I Seeing Things???

[Don Chichester]

IIRC, Edison was working with a strip of paper onto which telegraph impulses were burned, and could be re-played for transmission.  It was the idea of 'storage of sound impulses' that started Edison's experiment with tin foil.  The writer suggests that he started with paper, and worked on the concept for a year.  All info I have is that he tried tinfoil in August of 1877.  It worked the first time!  It was demonstrated for Scientific America in December 1877.  No year of research.
