Yorkshire and the Humber
Stainless steel was invented in 1913 by Harry Brearley of Sheffield, working for Firth Brown Steels (now called Sheffield Forgemasters). SAE 304 stainless steel is the most common stainless steel today, invented by Dr William Herbert Hatfield FRS in 1924 at Firth-Vickers known as Staybrite 18/8, a chromium-nickel steel. Many Swiss watches were mostly made out of Staybrite.
Robert L. Stevens
Stevens was president of the Camden and Amboy Railroad (C&A) in the 1830s and 1840s. When the "John Bull" steam locomotive arrived on the C&A property, it was originally named "Stevens" in his honor. Although his father is occasionally credited with the invention of the flanged T rail for railways, Robert Stevens at 42 is considered to have been the inventor of the first all-iron rail construction of the Camden & Amboy. Before 1831, the rails of all previous American railroads were strap iron rails made of wood with a metal strap applied to the wood. One of the two men had traveled to England to purchase the new rails since there was no rolling mill in the United States that was capable of producing the rails. The flat bottomed rail profile is used by railways of every nation. It replaced the cast-iron edge rails that had been introduced in England in 1789, which were made without flanges; instead, flanges were placed on the wheels. (The flanged T rail was introduced in England in 1836 by engineer Charles B. Vignoles (1793-1875), therefore the term "Vignoles rails" came into use in Europe).
