THOMAS ALVA EDISON, CO-SIGNED BY: WILLIAM A. HARDY
William A. Hardy, one of Thomas Edison's patent attorneys, signed this typed letter to Edison in 1923 regarding patents on vulcanized rubber. With a handwritten and signed note by Edison.
Typed letter signed "W. A. H" by Hardy in black ink and "TAE" by Edison in pencil. Lead and blue pencil notation at upper edge in unknown hand and purple ink date stamp in lower right corner. 1 page, 8½x11. Nov. 27, 1923. This letter was sent to Edison by Hardy and concerns a letter from Grasselli Chemical Co. notifying "the trade" about two patents the company has for vulcanized rubber. He added: "... You may be interested in vul-canizing rubber by some process which I do not know about, and which might render a consideration of these patents desirable." Edison wrote a short reply: "Has no bearing". HARDY was a patent attorney in the legal office of Thomas A. Edison, Inc. EDISON (1847-1931, born in Milan, Ohio) patented more than a thousand inventions, including the incandescent electric lamp, phonograph (his favorite invention), mimeograph, alkaline storage battery and microphone. In 1890, he invented the Vitascope, and Edison is credited with establishing the standard of using 35mm film with four perforations on the edges. He produced talking motion pictures in 1913. In 1887, Edison had set up his facility dedicated to research and development in West Orange, New Jersey. By the following year, it was the world's largest scientific testing laboratory. His original laboratory, in Menlo Park, New Jersey, was removed to the Greenfield Village Museum in Dearborn, Michigan by his friend, Henry Ford, in 1929. Light toned, soiled and creased. Pen skipped while signing Hardy's signature, which is still legible. Paper clip impressions and rust stains in upper left corner. Two file holes at top edge. Folded once and unfolded. Otherwise in fine condition.
