# Robert Hadfield

> Sir Robert Abbott Hadfield, 1st Baronet FRS was an English metallurgist, noted for his 1882 discovery of manganese steel, one of the first steel alloys. He also invented silicon steel, initially for mechanical properties which have made the alloy a material of choice for springs and some fine blades, though it has also become important in electrical applications for its magnetic behaviour.

*British metallurgist (1858–1940)*
