director Edith Craig. Hamilton played 'Woman' while Craig played the painter Rosa Bonheur, one of the 50 or so great women in the play. Lena Connell's photographs of the leading players were sold to assist the suffrage cause and Connell exhibited the pictures at the Royal Photographic Society in 1910-11. The play was produced all over the UK from 1909 until the First World War. Hamilton was a member of Craig's theatre society, the Pioneer Players. Her play "Jack and Jill and a Friend "was one of the three plays in the Pioneer Players' first production in May 1911. Hamilton inspired young schoolgirls, supportive of suffrage, like Winifred Starbuck, who had Hamilton and other leaders' pictures on her desk in purple, white and green frames and later herself protested by school disorder, such as graffiti and hiding the school registers and handbell, as a milder form of resistance to authority for women's suffrage. During World War I, Hamilton initially worked in the organisation of nursing care, with the Scottish Women's ambulance service near Paris, and then joined the army as an auxiliary. Later she formed a repertory company to entertain the troops. After the war, she wrote as a freelance journalist, particularly on birth control, and was a press officer for the Geneva International Suffrage Conference and as a playwright for the Birmingham Repertory Company. When Lena Ashwell Players Ltd was formed in 1923, Hamilton was one of the directors. The other three were Lena Ashwell, Esme Church and Marion Fawcett, who were the company's theatre managers. Hamilton was a regular contributor to Time and Time magazine, and an active member of the feminist Six Point Group, campaigning for the rights of children, widows and unmarried mothers; equal guardianship of children, and equal pay in teaching and civil service. In 1938, she was given a Civil List pension. She was a friend of E. M. Delafield and is thought to be the model for "Emma Hay" in Delafield's "Provincial Lady" books. Hamilton's "Theodore Savage" (1922, vt. Lest Ye Die 1928) is a science-fiction novel about a Britain devastated by a war. Hamilton's autobiography "Life Errant" was published in 1935. She died in Chelsea in 1952. In July 2017, the Finborough Theatre staged the first London production of Hamilton's play "Just to Get Married" in over 100 years.
