Margaret Haig Thomas was a businesswoman, suffragette and campaigner and has been described as one of Wales’ most remarkable political figures. The daughter of a coal industrialist, she used her privileged position in society to promote left-wing politics, feminism, literature and the arts. In 1920, she founded Time and Tide, a weekly magazine promoting feminist and left-wing causes, with a progressive all-female board. During a 1913 suffragist campaign led by the Women’s Social and Political Union, she attempted to blow up a letterbox and was subsequently imprisoned and went on hunger strike.
