Heini Halberstam (11 September 1926[1] – 25 January 2014[2]) was a British mathematician, working in the field of analytic number theory. He is one of the two mathematicians after whom the Elliott–Halberstam conjecture is named.[3]

Halberstam was born in Most, Czechoslovakia and died in Champaign, Illinois, USA. His father died when he was very young. After Adolf Hitler's annexation of the Sudetenland, he and his mother moved to Prague. At the age of twelve, as the Nazi occupation progressed, he was one of the 669 children saved by Sir Nicholas Winton, who organized the Kindertransport, a train that allowed those children to leave Nazi-occupied territory. He was sent to England, where he lived during World War II.[4]

He obtained his PhD in 1952, from University College, London, under supervision of Theodor Estermann.[5] From 1962 until 1964, Halberstam was Erasmus Smith's Professor of Mathematics at Trinity College Dublin (University of Dublin);[6] From 1964 until 1980, Halberstam was a Professor of Mathematics at Nottingham University. In 1980, he took up a position at the University of Illinois, Urbana Champaign (UIUC) and he became an Emeritus Professor at UIUC in 1996. In 2012, he became a fellow of the American Mathematical Society.[7]

He is known also for books, with Klaus Roth on combinatorial number theory,[8] and with H. E. Richert on sieve theory.[9][10]
