LEE de FOREST. Comprises: (1) TLS: "Lee de Forest", 1p, 7½x9½. Los Angeles, Calif., 1958 December 2. On his imprinted letterhead to Albert Jeffrey, Sr., Bedford, Indiana. In full: "I have just written your granddaughter (?), Ella May, and sent her a copy of my photograph - the only one I have here in the house. In reply to your question, I will state that I am a well known inventor of radio and that my basic invention made radio possible. I am enclosing a similar photograph to the one I sent to your granddaughter. I am sorry it is not 8 inches by 10 inches, as you requested, but you can have a local photographer enlarge it to 8 in. by 10 in. I shall be proud to have you do this. I was in the hospital last January, but have now completely recovered from that operation on my bladder. I am indeed fortunate to have recovered so well at my age of eighty-five. I note that you are eighty-one years old, and sincerely hope that you will reach and surpass my present age of eighty-five. I am the inventor of radio and television, but have had the good sense to live a decent life to which I attribute my survival from that operation. Thank you for your best wishes, which I warmly reciprocate. Cordially yours". Slightly creased. Stray ink smudge at lower margin at one line of type. Fine condition. (2) Photograph inscribed and signed: "Albert Jeffrey Sr./Best wishes/Lee de Forest". B/w, 3¼x4¼. Light paper clip impression at upper margin. Fine condition. In 1957, the year before he signed this letter, an 84-year-old de Forest had been issued his last patent. Lee de Forest (1863-1961) patented more than 300 inventions in wireless telegraphy, radio telephony, sound-on-film talking pictures, high-speed facsimile transmission, television, radiotherapy and related areas. One of his most important inventions was the triode Audion vacuum tube (patented in 1907) that was used in radios and televisions. The inventor demonstrated his discovery on January 20, 1910 with a broadcast of a live performance from New York City's Metropolitan Opera. By inventing the three-element vacuum tube, de Forest established the technology for all future telecommunication inventions, especially radio and television. He titled his autobiography, Father of Radio, but de Forest did not generally receive that recognition. Two items. Framed in the Gallery of History style: 30¼x18¾.
