George Ogurek Zimmerman, (October 20, 1935 – May 6, 2019) was a Polish-born American scientist, researcher, inventor, professor of physics and physics department chair at Boston University. Zimmerman achieved his PhD in solid state physics in 1963 at Yale University and came to Boston University in the fall of 1963. Zimmerman's major contributions in physics include discoveries in Condensed Matter and Solid State Physics, phase transitions at ultra low temperatures, magnetically intercalated graphite compounds, Jahn-Teller materials, and applied superconductivity and modeling. Zimmerman is also well known for his popular lectures on physics, hands-on advanced laboratory lectures and, a Summer Research Internship Program for High School students. Zimmerman's accomplishments were highlighted in the 17th edition of Who's Who in the World, the 7th through 10th editions of Who's Who in Science and Engineering, and multiple editions of Who's Who in America published between 1986 and 2016. He resided in Boston, where he enjoyed classical music and photography and pursued his research in physics and history until the end of his life. Zimmerman died at the age of 83 in 2019. Early life and education George Ogurek Zimmerman was born on October 20, 1935 in Poland. He received his Ph.D. in Physics from Yale University in 1963. His thesis was in experimental low temperature physics. After a few months as a post-doc with C.T. Lane at Yale, he joined the Physics Department at Boston University His research interests are in Condensed Matter and Solid State Physics. More specifically, some of the topics of interest are phase transitions, some at ultra low temperatures, magnetically intercalated graphite compounds, Jahn-Teller materials, and applied superconductivity and modeling. At Boston University, Zimmerman was department chair for 12 years, chaired the Faculty Council, and was a member and chair of several other influential university committees. His research collaborations include the Francis Bitter National Magnet Laboratory at MIT, and sabbaticals at Brookhaven National Laboratory, UC San Diego, Leiden University, the Netherlands, Harvard University, Cambridge US, and Imperial College, London. He was a Member At Large of the Governing Board of the Forum on the History of Physics (FHP) and its Webmaster ad hoc. He conducted many oral history interviews which have been archived at the Niels Bohr Library and Archives at the American Institute of Physics. He established a Summer Research Internship Program for High School students over 30 years ago. Biographical Listings American Men and Women of Science
