Mrs. Alford’s Nitro Factory
Businesswoman prospered in booming turn-of-century Pennsylvania oilfields.
In 1899, Mary Byron Alford, the “Only Woman in the World who Owns and Operates a Dynamite Factory,” prospered in the midst of America’s first billion-dollar oilfield. Mrs. Alford’s oilfield nitro factory cooked 3,000 pounds of nitroglycerin every day.
The 85,000-acre Bradford oilfield in north-central McKean County, Pennsylvania, and south-central Cattaraugus County, New York, remains an important part of U.S. petroleum heritage. There are many reasons, including Mary Alford’s pioneering oilfield career at the turn of the century.
Penn-Brad Oil Museum Director Sherri Schulze in 2005 exhibited a laminated (though wrinkled) newspaper article from 1899. “This was done by a student many years ago,” she said. “It was a school project done by one of Mrs. Alford’s descendants.”
