At the Age of 24...
Dame Agatha Christie 1890-1976
Florence Nighingale 1820-1910
In December 1844, in response to a pauper's death in a workhouse infirmary in London that became a public scandal, she became the leading advocate for improved medical care in the infirmaries and immediately engaged the support of Charles Villiers, then president of the Poor Law Board. This led to her active role in the reform of the Poor Laws, extending far beyond the provision of medical care. She was later instrumental in mentoring and then sending Agnes Elizabeth Jones and other Nightingale Probationers to Liverpool Workhouse Infirmary.
Dorothy Parker 1893-1967
After her limited schooling, she earned money by playing piano at a dancing school, among other things. She first sold a poem to Vanity Fair magazine in 1917, and some months later, she was hired as an editorial assistant for another Condé Nast magazine, Vogue. She moved to Vanity Fair as drama critic and staff writer following two years at Vogue.
