Donald R. Sadoway is the John F. Elliott Professor of Materials Chemistry in the Department of Materials Science and Engineering at the Massachusetts Institute of Technology. He obtained the B.A.Sc. in Engineering Science, the M.A.Sc. in Chemical Metallurgy, and the Ph.D. in Chemical Metallurgy, all from the University of Toronto. After a year at MIT as a NATO Postdoctoral Fellow, Dr. Sadoway joined the faculty in 1978. The author of over 150 scientific papers and holder of 23 U.S. patents, his research is directed towards the development of rechargeable batteries and environmentally sound technologies for the extraction of metals. To push these ideas from lab bench to marketplace, he is the founder of two companies, Ambri and Boston Electrometallurgical. With recordings of his chemistry lectures broadcast throughout the world on MIT OpenCourseWare, his impact on engineering education extends far beyond the lecture hall at MIT. Viewed over 1,600,000 times, his TED talk is a narrative about inventing inventors as much as it is about inventing technology. In 2012 he was named by Time magazine as one of the 100 Most Influential People in the World.
