Harry Brearley
Harry Brearley (18 February 1871 – 14 July 1948) was an English metallurgist, usually credited with the invention of "rustless steel" (later to be called "stainless steel" in the anglophone world).

The well told story is that Brearley noticed in his sample bin one of his pieces which had not shown signs of rusting after being exposed to air and water. This was further examined and analysed; a new steel, which he called "rustless steel", was born, the first commercial cast coming from the furnaces in 1913. Its name was changed the more euphonic "stainless steel" following a suggestion from Ernest Stuart of R.F. Moseley's, a local cutlery maker, and this eventually prevailed.
