      • Roger Keith Dennis (March 10, 1944 – December 12, 2024), known as R. Keith or Keith, was an American mathematician who worked in algebraic K-theory and group theory. His career was spent as a professor in the Department of Mathematics at Cornell University. Dennis was the executive editor of Mathematical Reviews as it transitioned from a printed resource to a mainly-digital one.


      Education and career


      Dennis was born on March 10, 1944 in Vernon, Texas, and grew up on a farm 8 miles north of Quanah, Texas. He graduated from Quanah High School in 1962, and attended Rice University, earning his bachelor's in 1966 and his doctorate in 1970.

      From Jan 1995 through Jun 1998, Dennis was the executive editor of the American Mathematical Society’s Mathematical Reviews. During this period Mathematical Reviews designed and began the development of MathSciNet which went online in January of 1996.
      He was on the Board of Advisors of the American Institute of Mathematics since its inception.
      In 2013, Dennis was in the inaugural class of fellows of the American Mathematical Society.
