description William Kelly Overview
William Kelly (1811-1888) was an American inventor and ironmaster who independently developed a pneumatic process for steelmaking in the 1850s. His method involved blowing air through molten iron to remove carbon impurities, similar to what became known as the Bessemer process patented by Henry Bessemer in England. Kelly received a U.S. patent for his process in 1857, though financial difficulties limited his ability to commercialize it effectively.
help William Kelly FAQ
What was William Kelly’s steelmaking process?
William Kelly developed a pneumatic process that blew air through molten iron to remove carbon and other impurities. The basic idea closely resembles the process later associated with Henry Bessemer.
Was William Kelly connected to the Bessemer process?
Kelly independently developed his method in the United States during the 1850s, while Henry Bessemer developed a similar process in Britain. Their work helped establish air blowing as a practical route from molten iron to steel.
When did William Kelly live?
William Kelly was born in 1811 and died in 1888. He worked as both an inventor and an ironmaster, so his experience included industrial production as well as experimentation.
Why is William Kelly less famous than Henry Bessemer?
The commercial success and wider promotion of the Bessemer process made Bessemer’s name more familiar. Kelly is still important because historical accounts recognize that he pursued a similar pneumatic steelmaking idea independently.
