By 1856, English genius Henry Bessemer had already become a renowned inventor. However, his needle die for postal stamps, sugar cane press and even centrifugal pump would not have immortalized his name for future generations. Bessemer was perpetuated thanks to the converter – the very thing he patented on October 17, 1856. Simply said, this is a furnace in which steel is produced from cast iron through blowing with technical oxygen or air. Bessemer’s furnace is still used today – after one and a half hundred years. A really tenacious invention!
