[Science & Technology] Thomas Edison's Laboratory Copy of a Patent for an Electric Light, 1881

(Washington, D.C.: United States Patent Office), February 15, 1881. Printed patent for Thomas A. Edison's Electric Light, patent No. 237,732. Two conjoined sheets. 4to. Illustrated with lithographed diagram of an electric light. Disbound; toned along edges.

From the collection of Charles L. Clarke and extracted from his bound collection of U.S. Patents granted to Edison. Clarke (1853-1941) was Chief Engineer and first President of the Edison Electric Light Company and was responsible for the Pearl Street Station in New York, the world's first commercial power plant. In February 1881, Edison established the headquarters of the Edison Electric Light Company in New York City, seeking to power lower Manhattan, which was achieved through the work of his engineers like Clarke.

The Edison Electric Light Company began operations on October 15, 1878. It was one of many business entities founded by Edison, and was a patent-holding corporate entity, backed by J.P. Morgan and the Vanderbilt family, for the purpose of funding Edison's experiments with the incandescent bulb and electric lighting.
