From The Guardian:
Harold Pinter, who has died at the age of 78, was the most influential, provocative and poetic dramatist of his generation. He enjoyed parallel careers as actor, screenwriter and director and was also, especially in recent years, a vigorous political polemicist campaigning against abuses of human rights. But it is for his plays that he will be best remembered and for his ability to create dramatic poetry out of everyday speech. Among the dramatists of the last century, Beckett is his only serious rival in terms of theatrical influence; and it is a measure of Pinter's power that early on in his career he spawned the adjective “Pinteresque” suggesting a cryptically mysterious situation imbued with hidden menace.
Pinter was born into a Jewish family in the London borough of Hackney. His grandparents were Jews who had fled persecution in Poland and Odessa. His father, Jack, was a hard-working tailor whose own family had artistic leanings: his mother, Frances, came from a convivial, extrovert and spiritually sceptical clan. And it was not difficult to trace in Pinter's own complex personality elements from both sides of the family. He balanced his father's faintly authoritarian nature with his mother's instinctive generosity.
Pinter was an only child: as a boy, he conducted conversations in the back garden with imaginary friends. But such circumstances conspired to give him a sense of solitude, separation and loss: the perfect breeding-ground for a dramatist. He was evacuated to Cornwall at the age of nine where he became aware of the cruelty of schoolboys in isolation. Back in London during the Blitz, he also absorbed the dramatic nature of wartime life: the palpable fear, the sexual desperation, the genuine sense that everything could end tomorrow. All this fed into his work as a writer: his memories of wartime London led to a particularly vivid 1989 screen adaptation of Elizabeth Bowen's The Heat of the Day.
