Hey folks
I have volumes 1 and 2 of this book by Francis Jehl, published in 1937. Jehl was a laboratory assistant to Edison in New Jersey during his work on the phonograph and electric lighting. Interesting history from the eyes of someone there during the efforts. I have duplicate copies, so thought I would offer to others.
Volume 1 covers the years prior to 1879, which includes the phonograph work. This volume has a cardboard backing. Volume 2 covers the early development of electric lighting, with Edison's distribution methodology being the central focus. This volume has a standard hardcover backing. I would say these volumes are in fair to good condition (no loose pages or markings).
I'd take $15 for them, plus shipping. If anyone is interested, just pm me.
Thanks. **SOLD**
