This rich biography tells the remarkable tale of Margaret Haig Thomas who became the Viscountess Rhondda. She was a Welsh suffragette, held important posts during the First World War and survived the sinking of the Lusitania. A leading British industrialist, she was also instrumental in securing a seat for women in the House of Lords. Closely associated with figures such as Winifred Holtby, Vera Brittain and George Bernard Shaw, she founded and edited the progressive weekly paper Time and Tide. Drawing upon a rich array of sources, many previously unused, Angela V. John explores both the public achivements and the fascinating private world of one of the movers and shakers of British society in the first half of the twentieth century.
