LADY Bullock, the widow of Alan Bullock, the celebrated historian and founding Master of St Catherine’s College, Oxford, has died aged 93.

Hilda Bullock — known as Nibby — served as a magistrate in Oxford between 1964 to 1985 and was a well-loved figure at St Catherine’s College, where her husband was Master for 28 years.

Lord and Lady Bullock, who for many years lived in Godstow Road, Upper Wolvercote, were married for 64 years.

Like her husband, she won a place at Oxford University and read English at St Anne’s College.

Lady Bullock was for many years an English teacher at Wychwood School, in North Oxford.

Her husband, who died in 2004 aged 89, established himself as one of the world’s best known historians with his book Hitler: A Study In Tyranny, and other major works like his biography of Ernest Bevin and Stalin: Parallel Lives.

Lord and Lady Bullock helped raise the equivalent of £32m in today’s money in one of Oxford’s most successful fundraising campaigns to create St Catherine’s College.

Lady Bullock was also a staunch supporter of her husband during his years as Vice-chancellor of Oxford University.

Once when students threatened to occupy the Clarendon Building in a demonstration over secret files, she famously made her own protest. She sat outside the building and symbolically read a copy of Kenneth Clark’s Civilisation.

She was one of the prominent activists in the Tin Hat campaign, which successfully opposed proposals to build a bypass in North Oxford.

Lady Bullock died at St Luke’s Nursing home in Oxford. A service is to be held on Friday, March 6, at 11am at Harris Manchester College, Oxford, prior to cremation at Oxford Crematorium.

She leaves three sons, seven grandchildren and a great granddaughter.
