Henry Quackenbush
From Wikipedia, the free encyclopedia
Henry Quackenbush (April 27, 1847 – September 8, 1933)[1] was an American industrialist. He founded the H. M. Quackenbush Company, a metal finishing company in Herkimer, NY, now called Whyco Finishing Technologies. He patented the extension ladder in 1867[2] and helped standardize shot size in guns. His company produced many models of air rifles. In 1913, Quackenbush invented the spring-jointed nutcracker, of which perhaps 200 million were made.[1] Metal nutcrackers seen today marked with HMQ or QBC were made by Quackenbush's company.
