Born into a working-class family 1936 in Birkhenhead, northwest England, Jackson trained at the Royal Academy of Dramatic Art in London. She performed with the Royal Shakespeare Company — where she starred in the cutting-edge drama “Marat/Sade” directed by Peter Brook — and became one of the biggest British stars of the 1960s and 70s, winning two Academy Awards, for “Women in Love” in 1971 and “A Touch of Class” in 1974.
