M. Shamsuddin, the former Professor and Head had a very long association (August 1971 – June 2010) with the Department of Metallurgical Engineering, Banaras Hindu University. He spent three years (June 1978 - June 1981) in the United States, one year each at the James Franck Institute, University of Chicago; Department of Metallurgy, University of Utah, Salt Lake City and Department of Materials Science and Engineering, Massachusetts Institute of Technology, Cambridge. At MIT he held the position of Visiting Associate Professor and taught a graduate course entitled “Physical Chemistry of Metallurgical Processes.” His field of specialization has been Chemical/Metallurgical Thermodynamics and Chemical-Extractive Metallurgy. He has conducted extensive measurements to determine thermodynamic properties of semiconducting intermetallics, binary and ternary alloy systems using calorimetric and electrochemical techniques. A few measures of the recognition of his outstanding researchcontributions include the Pandya Medal (1975), INSA Young Scientist Award (1975), Visiting Associate Professor at MIT (1981), Best Metallurgists Award (1993) from the Ministry of Steel & Mines, Government of India and MRSI Medal (1995).          After retirement from the faculty in June 2010 he started working on book writing. The first edition of “Physical Chemistry of Metallurgical Processes” was published in February 2016 and the second edition appeared in June 2021.
