Group of three albumen stereoviews depicting Thomas A. Edison in laboratory and domestic settings, including a portrait of Edison in his laboratory surrounded by electrical apparatus and glassware, Edison standing beside a large dynamo at the Edison works in Orange, New Jersey, and Edison posed with family members at the Llewellyn Park residence. Published views include examples by the Keystone View Company, H.C. White Co., and Underwood & Underwood. The stereographs appear to date from the late nineteenth and early twentieth century based on mount style and printed publication information. Thomas Alva Edison (1847–1931) was one of the most influential American inventors, known for the development and commercialization of the electric light, phonograph, and motion picture technologies. The laboratory views illustrate the industrial and experimental environments associated with Edison’s work, while the family portrait shows the inventor in a domestic setting that was frequently reproduced for educational stereograph series. The Keystone stereoview mount includes a printed descriptive text panel on the reverse titled “The Most Famous Inventor of the Age, Thomas A. Edison in His Laboratory,” providing a biographical summary of Edison’s life and inventions. The laboratory stereoview is numbered H218 on the mount. Another view is numbered 537.8 and 973.01. Manufacturer and publisher imprints appear along the mount edges, including Keystone View Company and Underwood & Underwood. The family view includes a printed caption identifying Edison with his family at Llewellyn Park, New Jersey.
