[3] Bentham worked in London hospitals for a short time,[1] before entering general practice in Newcastle upon Tyne and Gateshead with Dr Ethel Williams,[1] the first female doctor in the city, and a radical suffragist.
[5] Bentham was active in pursuing NUWSS support for a joint Suffrage-Labour Parliamentary candidate,[5] a campaign which in 1912 resulted in the creation of the Election Fighting Fund.
In 1909, Bentham moved to London, where she lived with Marion Phillips[2] in Holland Park,[1] her home serving as a meeting place for like-minded women.
[citation needed] In 1911, Bentham was a driving force behind the establishment of a mother and baby clinic in North Kensington,[5] founded by the Women's Labour League in memorial to Margaret MacDonald and Mary Middleton.
[2] After World War I she was appointed a magistrate, one of the first women in the role,[1] working in the children's courts and serving on the Metropolitan Asylums Board.
[8] She died on 19 January 1931, at her flat in Beaufort Street, Chelsea, just after her 70th birthday, as a result of heart failure following influenza, and was cremated in Golders Green.
