Artifact Overview
Alonzo G. Decker and S. Duncan Black, who operated a small manufacturing company in Baltimore, Maryland, began designing and producing electric tools in 1916. Their pistol-style grip and trigger switch, patented the following year, set the standard for power tool design. Black & Decker developed new products as the company expanded through the 1920s, introducing an electric hammer in 1929.
