On the 7th of December, 1919, The New York Tribune ran a feature on Lady Astor, who was elected member of the British parliament for Plymouth (I think) to take the place her husband had to surrender due to his translation to the House of Lords. But during the war (the First World War) she was active in nursing and cheering soldiers.
Her husband went into the army and became Major Astor. She went to work for the soldiers. The magnificent Astor estate of Cliveden, Taplow, one of the finest along the Thames, was turned into a hospital and rest cure, and she did not spare herself at nursing and visiting and cheering up the sick and wounded soldiers. After America went into the war, she could be found two evenings a week at an American officers’ club and two other evenings were passed at club for enlisted men, where she could be seen sitting on the floor playing the ukulele. She is said to be the only member of the British peerage who has mastered that instrument.
… and Lady Astor was for prohibition.
