Ernestine Mills (née Bell; 1871–1959) was an English metalworker and enameller who became known as an artist, writer and suffragette. She was the author of The Domestic Problem, Past, Present, and Future (1925). Three pieces of jewellery that Mills created for the suffragettes are in the Museum of London.
Mills was born in Hastings to Emily "Mynie" Ernest Bell (née Magnus; c. 1839 – 1893), an actor and classical musician, and her husband, Thomas Evans Bell, a writer. Mynie and Thomas Bell were both members of the Central Committee of the National Society for Women's Suffrage. Mynie Bell was one of the signatories of the 1866 petition, organised by Barbara Bodichon, asking that all householders be given the vote.
After her parents died, she was supported for a time by guardians, William Edward and Hertha Ayrton. She attended the Slade Art School, Finsbury Central Technical School, and South Kensington School of Art. An apprentice to Frederic Shields, she also studied enamelling under Alexander Fisher. She acted as vice-president for the craft section of the Society of Women Artists for a period.
Mills married the doctor Herbert Mills (1868–1947), who shared her Fabian views and was physician to Richard and Emmeline Pankhurst. They had a daughter, Hermia Mills (1902–1987), who became a doctor.
In 1907 Mills joined Emmeline Pankhurst's Women's Social and Political Union (WSPU) and by 1909 had joined the Fabian Women's Group. According to the British National Archives, Mills was possibly the woman on the ground in the photograph on the Daily Mirror front page on 19 November 1910, the day after the "Black Friday" suffragette demonstration outside the House of Commons.[a] The photograph was published under the headline: "Violent Scenes at Westminster Where Many Suffragettes Were Arrested While Trying to Force Their Way Into the House of Commons." Other sources have identified the woman as the suffragette Ada Wright.[b]
The Museum of London holds three pieces of jewellery Mills made for the suffragettes. One is an enamel-and-silver pendant of winged Hope singing outside prison bars with semi-precious stones of purple, green and white,  created to celebrate the release from prison of Louise Eates, Honorary Secretary of the Kensington branch of the WSPU. The other two are brooches, one in the WSPU colours, with the words "Votes for Women" in white on a green wreath and purple background, and the second, made for the Women's Freedom League (WFL), reads "Votes for Women" in the WFL colours: green, white and gold.
- The National Archives Catalogue: "Reference: COPY 1/551/264: 'Photograph [of] lady lying on ground, policeman looking at her, other figures near'. [Suffragette movement. Black Friday demonstration, 18 November 1910. There is some dispute over the identity of the parties depicted. Some sources have identified Mrs Ernestine Mills prone and Dr Herbert Mills in top hat. However, there is contemporary testimony to the effect that it is Ada Wright prone]".
- These include Georgiana Solomon in a letter to Home Secretary Winston Churchill on 17 December 1910; Sylvia Pankhurst in her book The Suffragette Movement (1931); Ada Wright herself in an interview published in 1973; suffrage researcher Caroline Morrell; and the historians Diane Atkinson and Elizabeth Crawford. In her reference guide to the women's suffrage movement, Crawford writes "The front page of the Daily Mirror of 19 November shows Ada Wright lying on the ground, a tiny cowering figure. The chief commissioner of police expressed the opinion that he thought from the smiling expression of a boy seen in the background, and from the fact that there was not a dense crowd around the police, that the woman had simply sunk to the ground exhausted with struggling with the police. The picture in the 25 November issue of Votes for Women shows that the police are holding back a large crowd, a man who had come to Ada Wright's aid has been seized by the police, and another policeman is bending over her, apparently about to grasp her by her upheld arm. Ada Wright's predicament produced the iconic image of 'Black Friday'. She reported that the government suppressed copies of the Daily Mirror and ordered negatives of the photographs to be destroyed. The WSPU made full use of its moral advantage and used a photograph of the incident in Leaflet 75—'Plain Facts about Suffrage Deputations'."
