Negaunee – NMU professor emeritus and historian Russell Magnaghi and NMU alumnus James Shefchick will present their new biography “Tsu-Ming Han: Man of Two Different Worlds” a with a brief public program and book signing on Saturday, February 4 beginning at 11 a.m. at the Michigan Iron Industry Museum in Negaunee.
The late Tsu-Ming Han was a brilliant scientist who helped to save the economy of central Marquette County. Han fled China in the late 1940s, just before the Communist takeover, and immigrated to the United States to complete graduate studies in geology. He later was instrumental in developing lower-grade iron ore refinement processes and pelletization for Cleveland-Cliffs Iron Company.
Han’s notable discovery of the “world’s oldest megascopic fossil” gave the Upper Peninsula an important claim to fame. He presented his findings at the Geological Society of America in 1991 and collaborated with a UCLA professor on a related publication. He published and presented numerous papers on iron geology.
Han’s wife, Joy, had a similar exit from China. She still lives in Ishpeming, where the couple raised children Dennis, Timothy and Lisa.
