VF+, minor fold soil on the back only. Lee DeForest (1873-1961) was one of the most productive and controversial inventors of the 20th Century. Although he worked for several companies, including Western Electric, most of his life was spent as an independent inventor, for which he received over 180 patents. He is most known for his pioneering work with the vacuum tube, first as a detector of radio waves, then as an amplifier for long distance phone calls and finally as the major technology of the radio transmitter. He received an honorary Oscar in 1959 for his Phonofilm process, a way to make the movies talk.
