While many are aware of the Bessemer process which turned pig iron into the more malleable, workable steel, it was invented and patented by Henry Bessemer. But most are unaware that William Kelly actually invented the process before Bessemer; it was alleged that some of Kelly's workmen informed Bessemer of Kelly's process. Bessemer patented his process in 1857 but in 1871 the US Patent Office granted Kelly a renewal, and rejected applications for renewal by Bessemer. Kelly was one of the giants who helped propel the Industrial Revolution. A genuine treasure for the student and collector of Industrial History. Very good. Item #17633
