Adeline Chapman

Adeline Mary Chapman (née Chapman; 27 August 1847 – 20 January 1931), first married name Adeline Guest, was an English campaigner for women's suffrage. She was a suffragist, and opposed the militancy of the suffragettes. Having been an early member of the Women's Social and Political Union, she was a member of the Central Society for Women's Suffrage from 1901. Unhappy with what she perceived as the ineffectiveness of the National Union of Women's Suffrage Societies (NUWSS), the main suffragist organisation, she was the founding president of the New Constitutional Society for Women's Suffrage (NCS).

The aim of the NCS was to lobby government, campaign against the governing Liberal Party candidates (as the party was then broadly anti-women's suffrage) and to explicitly "abstain from public criticism of other suffragists". From 1916, as president of the NCS, she attended the Consultative Committee of the Women's Constitutional Suffrage Societies: the aim of the Consultative Committee was successfully realized in the Representation of the People Act 1918 which gave the right to vote to women aged over 30 for the first time. With the rights for some women to vote obtained, the NCS dissolved in June 1918.
