Summary:This series describes Sperry's inventions and entrepeneurial activities in the two decades (1880-1900) when he was considered one of America's electrical pioneers. It documents his efforts to develop arc lighting systems, stationary power, mining machinery, and electric traction. The records describe the operation of the Sperry Electric Light, Motor, and Car Brake Company, which was founded in 1883 to set up electric power stations and manufacture component parts. These are fragmentary, but they do contain copies of Sperry's agreements with his financial backers and correspondence that traces his efforts to patent his inventions and secure customers
