Paul D. Seymour, born in 1950 in Plymouth, England, is a British mathematician known for his work in discrete mathematics, especially graph theory. He was responsible, with others, for important progress on regular matroids and totally unimodular matrices, the four colour theorem, linkless embeddings, graph minors and structure, the perfect graph conjecture, the Hadwiger conjecture, claw-free graphs and the Erdős-Hajnal conjecture. He studied at Exeter College, Oxford, gaining his D.Phil. in 1975 under Aubrey William Ingleton, and is now the Albert Baldwin Dod Professor of Mathematics at Princeton University. He won the Fulkerson Prize in 1979, 1994, 2006 and 2009, the Ostrowski Prize in 2003, and became a Fellow of the Royal Society in 2022.
