Paul Schupp

Paul Eugene Schupp (March 12, 1937 – January 24, 2022) was an American-born British professor emeritus of mathematics at the University of Illinois at Urbana Champaign. He is known for his contributions to geometric group theory, computational complexity and the theory of computability.

He received his Ph.D. from the University of Michigan in 1966 under the direction of Roger Lyndon.

Together with Roger Lyndon he is the coauthor of the book "Combinatorial Group Theory" which provided a comprehensive account of the subject of Combinatorial Group Theory, starting with the work of Dehn in the 1910s and to late 1970s and remains a modern standard for the subject of small cancellation theory.

In 1977, Schupp received a Guggenheim Fellowship. In 2012, he was named an inaugural fellow of the American Mathematical Society. In 2017, the conference "Groups and Computation" was organized at Stevens Institute of Technology celebrating the mathematical contributions of Paul Schupp. Schupp died on January 24, 2022, at the age of 84.
