Peter Swinnerton-Dyer, English mathematician and academic (died 2018)

Sir Henry Peter Francis Swinnerton-Dyer, 16th Baronet, was an English mathematician specialising in number theory at the University of Cambridge. As a mathematician he was best known for his part in the Birch and Swinnerton-Dyer conjecture relating algebraic properties of elliptic curves to special values of L-functions, which was developed with Bryan Birch during the first half of the 1960s with the help of machine computation, and for his work on the Titan operating system.
