The Society of Women Musicians was a British group founded in 1911 for mutual cooperation between women composers and performers, in response to the limited professional opportunities for women musicians at the time. The founders included Katharine Emily Eggar, a composer, Marion Scott, a musicologist, and Gertrude Eaton, a singer. 37 women came to the first meeting, including Rebecca Helferich Clarke and Liza Lehmann, who later became the group's first president. The Society disbanded in 1972, and its archives were given to the Royal College of Music.
