Thomas William Körner (born 17 February 1946) is a British pure mathematician and the author of school books. He is titular Professor of Fourier Analysis in the University of Cambridge and a Fellow of Trinity Hall. He is the son of the philosopher Stephan Körner and of Edith Körner.

He studied at Trinity Hall, Cambridge, and wrote his PhD thesis Some Results on Kronecker, Dirichlet and Helson Sets there in 1971, studying under Nicholas Varopoulos.[1] In 1972 he won the Salem Prize.[2]

He has written three academic mathematics books aimed at undergraduates:

  • Fourier Analysis[3]
  • Exercises for Fourier Analysis
  • A Companion to Analysis

He has also written two books aimed at secondary school students, the popular 1996 title The Pleasures of Counting and Naive Decision Making (published 2008) on probability, statistics and game theory.
