The JILA and NIST communities are recently saddened by the passing of physicist James 鈥淛im鈥 E. Faller. Faller was a visionary whose scientific contributions have contributed to our understanding of the universe. Faller鈥檚 work as a JILA Fellow spanned over 50 years (since 1972), and he remained actively engaged in the scientific research process, serving as NIST QPD Division Chief for a time. With heavy hearts, we bid farewell to a brilliant mind, a passionate explorer, and a respected member of the scientific community.
