EXTRACTS

 Ann Mitchell, who has died of Covid-19 in a care home aged 97, worked at the heart of the code-breaking nexus in Hut 6 at Bletchley Park during the Second World War.

Ann Katharine Williamson was born in Oxford on November 19 1922, the eldest child of Herbert Williamson, a former commissioner with the Indian Civil Service in Simla, and his wife Winifred (née Kenyon), who helped to run one of Britain’s first family planning clinics.

On VE-Day in 1945, she and her colleagues at Bletchley were told that their services were no longer required. She went on to work as a secretary at an Oxford college and in 1948 married Angus Mitchell, who had been studying History at Oxford after wartime service in which he won an MC. The couple moved to Edinburgh, where he got a job in the Scottish Office and they brought up four children.

Ann Mitchell’s husband died in 2018 and she is survived by their two sons and two daughters.
