It is with great sadness that we inform you of the death of our mentor, colleague, and friend Hans-Peter Kuenzle. Hans passed away on September 12, 2019, in Edmonton, Canada.
Hans was born in Kreuzlingen, Switzerland, in 1940. After undergraduate studies at ETH (Zuerich), where one of his mentors was Heinz Hopf, he moved on to King’s College London where he received his PhD in 1967 under the supervision of Prof Hermann Bondi. Hans held a postdoctoral appointment at UC Berkeley before joining the University of Alberta in 1970. He was promoted to Full Professor in 1980 and retired from the University of Alberta in 2006.
Hans made important contributions in mathematical relativity. He was well-known for his work on the geometric formulation of the Newtonian limit, the uniqueness problem for the static fluid ball, and the Einstein-Yang-Mills equations. His co-discovery of the SU(2) coloured black hole solutions of the static Einstein-Yang-Mills equations was among his best-known and most influential results.
Hans is survived by his wife Nicole and their four children.
