Michael G. Rossmann (30 July 1930 – 14 May 2019) was a German-American physicist, microbiologist, and Hanley Distinguished Professor of Biological Sciences at Purdue University who led a team of researchers to be the first to map the structure of a human common cold virus to an atomic level. He also discovered the Rossmann fold protein motif. His most well recognised contribution to structural biology is the development of a phasing technique named molecular replacement, which has led to about three quarters of depositions in the Protein Data Bank.
