Sir Alexander Oppenheim was born in Salford, Lancashire, his first language being Yiddish. After graduating from Oxford in 1927, he gained a Chicago PhD in 1930 with a thesis

After a year lecturing at Edinburgh University, he accepted a professorship at the Raffles College, Singapore. During the war he was a prisoner at the Changi camp.

After the war he returned to Raffles College, retiring in 1967. He then became a professor at Reading University (1966-68) and head of the mathematics departments of the University of Ghana (1968-73) and Benin, Nigeria (1973-77).
