Tokuhichi Mishima

Tokuhichi Mishima (三島 徳七 "Mishima Tokuhichi", February 24,1893 – November 19,1975) was a Japanese metallurgist. He discovered that aluminum restored magnetism to non-magnetic nickel steel. He invented MKM steel, which was an extremely inexpensive magnetic substance that has been used in many applications. It is also closely related to the modern Alnico magnets. He later became a professor at the Tokyo Imperial University. He received the Blue Ribbon Award and the Large Asahi Ribbon Award.
