The Women's Radio Corps (WRC) was established by Edna Owen (generally credited under her husband's name, Mrs Herbert Sumner Owen) and an advisory council during World War One. The aim of this branch of the US Army Signal Corps was to recruit women to train as wireless operators, in order to replace male wireless operators who had gone to war. The activities of the Corps converged with the wartime wireless activities and training of the National League for Women's Service whose training classes were directed by Owen.
