His mother, Julie Brett (née Josie Dalglish; 1925–2015),8 was a ballet dancer and socialite, and his father, Eric Selig Phillip Cowell (1918–1999), was an estate agent, property developer, and music industry executive.9 Cowell’s paternal grandmother was a Polish Jew, who emigrated with her family to the UK in 1915.1011 Cowell’s paternal grandparents married at West Ham Synagogue in 1915.12 His father was from a mostly Jewish family, though he did not discuss his background with his children, and his mother was from a Christian background.1113 He has a younger brother, Nicholas Cowell, three half-brothers, John, Tony, and Michael Cowell, and a half-sister, June Cowell.
Cowell attended Radlett Preparatory School and the independent Dover College, as did his brother, but left after taking GCE O levels. He passed English Language and Literature, and then attended Windsor Technical College, where he gained another GCE in Sociology.14 Cowell took a few menial jobs—including, according to his brother Tony,15 working as a runner on Stanley Kubrick’s 1980 horror film The Shining—but did not get along well with colleagues and bosses, until his father, who was an executive at EMI Music Publishing, managed to get him a job in the mail room. However, after failing to get a promotion, he left to try out other jobs before returning to EMI.
