In this photo from a 1926 biography of Hertha Ayrton (1854-1923), captioned "Mrs. Ayrton in her laboratory," the British scientist and inventor stands in the "lab" in her own home where she conducted all her experiments. Ayrton was the first woman to be proposed for fellowship of the British Royal Society, but her candidacy was denied on the grounds that as a married woman she had no legal existence in British law.
