is Harry Brearley's birthday. Brearley was an English metallurgist who discovered "rustless steel" or stainless steel. He was searching for a new steel to use to minimize corrosion of gun barrels that would still resist the high temperatures and pressures associated with firing a gun. He discovered that if he added chromium and nickel to ordinary carbon steel, a thin layer of protection from rust appeared.
