George Rossman, Caltech professor of mineralogy, emeritus, passed away on February 6, 2026. He was 81.
The unifying theme of his research career was a simple, relatable question: Why do gems and other minerals possess their distinctive colors? He also studied the distribution of water in minerals of the deep earth, electronic structure, etc.
