We at Brown Physics are mourning the loss of our beloved colleague, Charles Elbaum, who passed away Sunday, March 4, 2018.

Professor Elbaum received his Master’s and Ph.D.degrees from the University of Toronto. After serving in research fellowships at the University of Toronto and at Harvard University, he joined the Brown faculty as Assistant Professor of Applied Physics in 1959. During his distinguished career, he made many important contributions to the field of condensed matter physics, particularly, at very low temperatures. He was a leading expert in the properties of quantum solid and liquid helium, crystal defects and their interactions, diffusion in solids, ultrasonic waves and acoustics in solids, metallurgy, superconductivity, and vortex dynamics near the superconducting phase transition.  He was a prolific author of many highly-cited scientific papers, books, and book chapters.  He was a beloved teacher and mentor to countless students and a valued colleague and leader to the faculty and staff in the Department of Physics and the larger Physics community.  A Fellow of the American Physical Society, he served as Chair of the Physics Department from 1980 to 1986. He was appointed the Hazard Professor of Physics in 1991. He officially retired from his tenured position in 2001 but remained active as a Professor of Physics (Research) for many years. 

Our deepest condolences to Professor Elbaum's family, friends, and colleagues.
