Thomas A. Edison...

SCIENTIFIC AMERICAN, New York, July 6, 1878  The ftpg. has a large illustration captioned: "Electrical Indicator for Showing the Rotation of the Earth" with a related article (see images). But the prime content of this issue is the nice one-third pg. illustration captioned: "The Phonograph and Its Inventor, Mr. Thomas A. Edison." showing a young Edison with his newly invented & crude looking device which was his phonograph. There is a related article on the same page headed: "Mr. Thomas A. Edison" which includes: "...Every one is acquainted with his telephone, phonograph & other remarkable inventions...Mr. Edison is above the medium height & although he is only 31 years old, his iron gray hair & thoughtful eye show the effects of continued study. He is genial, liberal, and entirely unostentatious. His mind, day and night, is on his projects..." with more (see photos). Further to the back of the issue is over a full page article headed: "Edison's Telephonic Researches" which includes 11 illustrations (see). Complete in 16 pgs. and in unusually nice condition.
