Duncan Black: Inventor and Co-Founder of Black & Decker
Early Life and EducationBorn on August 2, 1883, in Baltimore, Maryland, S. Duncan Black hailed from a middle-class family. After graduating from Baltimore Polytechnic Institute as a draftsman, he embarked on a path that would lead him to revolutionize the power tool industry.
Partnership with Alonzo Decker
In 1906, Black crossed paths with Alonzo Galloway Decker, a tool and die maker. Together, they pooled their resources in 1910 and established a small machine shop. Initially, their company produced various custom-made devices, such as milk bottle capping machines and candy dipping equipment.
The Invention of the Pistol Grip Drill
A breakthrough came in 1914 when Black and Decker improved the first-ever electric tool: the motor-driven hand drill. They introduced the novel concept of a pistol grip and trigger switch, enabling the tool to be operated with one hand. This innovation transformed the industry, making power drilling more accessible and convenient.
Black & Decker's Growth and Success
In 1916, Black and Decker launched production of their drills. The following year, they opened a 12,000 square-foot factory in Towson, Maryland. Their product line expanded to include the Lectroflater, the company's first official branded tool. By 1920, Black & Decker's annual sales exceeded $1 million, and they established offices in multiple cities and a factory in Canada.
Industry Leadership and Innovation
Black & Decker continued to innovate throughout its history. Duncan Black held 14 patents, including for the electric drill. The company expanded beyond industrial and professional power tools to become the world's largest manufacturer of electric power tools for consumers. They introduced the first line of DIY power tools in 1946 and the first cordless power tool in 1961.
Legacy
S. Duncan Black served as president of Black & Decker from 1910 until his death in 1951. Under his leadership, Black & Decker acquired numerous companies and eventually merged with Stanley Works in 2010, becoming Stanley Black & Decker. His contributions to the power tool industry are enduring, leaving a lasting impact on the way people work and create.
Personal Life
In 1903, Duncan Black married Anna Ridgeley Black (née Talbott). They had three children: Elizabeth Black Apsey, Alice Black Lewis, and Samuel Duncan Black. Black passed away on April 15, 1951, in Towson, Maryland.
