She was born at 89 Priory Road, West Hampstead, London NW6. Her parents were Meyer Max Heinemann, a merchant banker, and Selma Schott, both non-Orthodox Jews from Frankfurt, Germany.^[2] Heinemann was educated at Roedean School and at King Alfred School in London, and read English at Newnham College, Cambridge from 1931, later graduating from Cambridge University with a BA with first class honours.^[1] She was the lover of John Cornford while a student. The historian Eric Hobsbawm, who studied at Cambridge at the same time, wrote "she probably had more influence on me than any other person I have known."

She joined the CPGB in 1934,^[1] because of its active opposition to the British Union of Fascists.

After Cambridge she taught 14-year-old girls at Cadbury's Continuation School in Bournville, now Bournville College, on day release from the chocolate factory.^[1] In the CPGB she worked in the Labour Research Department from 1937.

She stood as the communist candidate for Vauxhall Constituency in the 1950 General Election.^[1]

In 1959 she resumed teaching at Camden School for Girls and then Goldsmiths College from 1965 to 1977.^[1] In 1976 she was made a Fellow of New Hall, Cambridge (now Murray Edwards College).^[1] She was still teaching at New Hall up to 1989 and stayed with the CPGB until it was dissolved in 1991.

She had a child (Jane, born 1953) with John Desmond Bernal.^[3]
