John Paul Hempel (October 14, 1935 – January 13, 2022[1]) was an American mathematician specialising in geometric topology.

Early life and career

Hempel was born in Salt Lake City, Utah. In 1957 he graduated from the University of Utah with a degree in mathematics. In 1962, he defended his thesis at the University of Wisconsin-Madison, under the supervision of R. H. Bing.[2] He was a professor at Rice University until the time of his death.[1]

In 2013, Hempel was elected a fellow of the American Mathematical Society.[3]

Research

He also introduced the study of the curve complex into 3-manifold topology.[4]

Hempel wrote a book about 3-manifolds in 1976.[5]

Personal life

He was married to Edith, whom he married on September 1, 1965, in Houston, Texas; they had one son.[1]
