Mark B. Wise, a co-architect of heavy quark effective theory and a fixture of Caltech's campus for more than four decades, died July 10. He was 72.

Wise held the John A. McCone Professorship of High Energy Physics and helped develop the framework that lets physicists make precise predictions about the strong nuclear force, the most powerful of nature's fundamental forces. That force acts as the subatomic glue binding quarks into protons and neutrons, and binding those particles into atomic nuclei.

Caltech announced his death on July 13. No cause of death was given.

Hirosi Ooguri, who chairs Caltech's Division of Physics, Mathematics and Astronomy, called Wise a distinguished scientist deeply committed to his students and postdoctoral scholars. "He was also a kind and generous colleague whose counsel I always valued. I will miss him," Ooguri said.

44 years in Pasadena

Wise joined Caltech as an assistant professor in 1982 after earning his PhD from Stanford University in 1980 and serving as a junior fellow at the Harvard Society of Fellows. He rose quickly: associate professor in 1984, full professor in 1985, McCone Professor in 1992.

Born in Montreal on November 9, 1953, Wise earned his bachelor's and master's degrees from the University of Toronto in 1976 and 1977. Over his 44-year tenure in Pasadena, he supervised more than three dozen graduate students.

Honors and Hollywood

The American Physical Society awarded Wise its J. J. Sakurai Prize for Theoretical Particle Physics in 2001. He shared the honor with Nathan Isgur and Mikhail Voloshin for their collective work constructing the heavy quark mass expansion and discovering heavy quark symmetry in quantum chromodynamics.

Wise was elected to the National Academy of Sciences and the American Academy of Arts and Sciences, and was named a fellow of the American Physical Society in 2003. Earlier in his career, he held an Alfred P. Sloan Foundation fellowship from 1984 to 1987.

His interests extended beyond the blackboard. Wise published work on mathematical models for finance and risk assessment, and served as the science consultant for the 2010 film Iron Man 2.

Caltech said a full obituary will be posted at a later date. No memorial service or campus tribute has been announced. The university's media contact for further information is Whitney Clavin at (626) 395-1944.
