Aloha Pat Henry

J. Patrick Henry

Long-time IfA faculty member J. Patrick Henry retired on September 1. An expert on the cosmological evolution of clusters of galaxies, he pioneered the use of X-ray observations of clusters to understand how the Universe grows. His work provided some of the earliest evidence for what has become the standard description of that growth, notably that there is less matter in the Universe and it is more evenly distributed than previously thought. He was also known for his lively Astronomy 110 classes, including paying students for correct answers during class.

Henry won several international awards, including a 2003 Humboldt Research Award for Senior U.S. Scientists from the German Alexander von Humboldt Foundation and the 2008 Bruno Rossi Prize of the High Energy Division of the American Astronomical Society, the most prestigious international award in the field of high-energy astrophysics. In 2011, he received the Regents’ Medal for Excellence in Research from the University of Hawai‘i. He was recognized as a “Highly Cited Researcher” by the publishers of Science Citation Index in 2003.

Henry received his PhD from the University of California, Berkeley in 1974. Before coming to Hawai‘i in 1981, he worked at the Smithsonian Astrophysical Observatory in Cambridge, Mass., where he developed the High Resolution Imager for the Einstein X-ray Observatory.

Henry intends to learn to sail and to read all the books he hasn’t had time to read over the last 40 years.
