Jennifer Louise Worth RN RM (née Lee; 25 September 1935 – 31 May 2011) was a British memoirist.

A television series, Call the Midwife, based on her books, began broadcasting on BBC One in the UK on 15 January 2012 and on PBS in the US on 30 September 2012.

With the Sisters of St John the Divine, an Anglican community of nuns, she worked to aid the poor.

She argued that the method shown in the film, far from being fairly quick and painless, was in fact almost invariably fatal for the woman.

As a result of the harm done with such illegal procedures, she approved of the legalization of abortion in the UK, saying this was a medical, not moral, issue.

[2] The first episode of the television series Call the Midwife, based on her experiences in Poplar, London, in the late 1950s, was dedicated to her.
