Typed Manuscript, "Lee de Forest: Inventor of the Three-Electrode Vacuum Tube," carbon with frequent manuscript emendations, 157 pp rectos only, 4to, New York, 1930, title leaf torn, housed in a period file folder with the author's address and identifying this as the "first / carbon copy."
"THE INSIDE STORY OF THIS TUBE": UNPUBLISHED BIOGRAPHY OF LEE DE FOREST GIVING A HISTORY OF THE INVENTION OF THE TRIODE, the three-electrode vacuum tube which propelled consumer electronics forward. "By placing a wire 'grid' between the cathode and anode, de Forest transformed Fleming's rectifier into an amplifier. With amplification, radio communications blossomed and long-distance telephony became a reality" (Vardalas "Twists and Turns in the Development of the Transistor," 2003). This monograph was written by a close friend of De Forest on the occasion of the 25th anniversary of the invention.
This lot includes a copy of a letter from De Forest to Thompson explaining the context of the manuscript: "...It has long been a wonder to me that no one has ever told the inside story of this tube ... Surely you know the detailed history, the romance, the adventures, and the hardships I faced. So go for it."
