Aubrey William Ingleton (1920–2000) was an English mathematician.

Ingleton was born in Chester, the son of an accountant. He joined the civil service at age 16, and during World War II was seconded to a radar development project. After the war, he entered Northern Polytechnic, and earned a B.Sc. in mathematics in 1949 as an external student at the University of London, winning first class honours, the Lubbock Prize, and the Sherbrooke Prize.[1] He did his graduate studies in mathematics at King's College London under the supervision of Anthony Francis Ruston, on subjects related to the Hahn–Banach theorem.[1][2] He took a faculty position at Birkbeck College in 1951, and married in 1952. In 1961 he moved to New College, Oxford, as the Mathematics Tutor. In 1966 he took up a Chair in Pure Mathematics at Cardiff University, but he returned to Oxford in 1967, becoming a fellow of Balliol College, where he remained for the rest of his career.[1] Among his students at Oxford was Paul Seymour.[2]

As a mathematician his works are related to many different topics in Analysis, Geometry, Algebra, Topology, Combinatorics and Algebraic Geometry. His work on matroids culminated in the paper "Representation of matroids" published in 1969. In his work Ingleton studied matroids as a generalization of the concept of linear independence. The paper is a survey about representable matroids as it exhibited matroids representable over C but not over R and similarly over R but not over Q. He included in his paper a single theorem which is a necessary condition of the representability of matroids. This condition is known in the literature as Ingleton's Inequality.[1]
