Florence's desire to have a career in medicine was reinforced when she met Elizabeth Blackwell at St. Bartholomew's Hospital in London. Blackwell was the first woman to qualify as a doctor in the United States. Blackwell, who had to overcome considerable prejudice to achieve her ambition, encouraged her to keep trying and in 1851 Florence's father gave her permission to train as a nurse.
Florence, now thirty-one, went to Kaiserwerth, Germany where she studied to become a nurse at the Institute of Protestant Deaconesses. Two years later she was appointed resident lady superintendent of a hospital for invalid women in Harley Street, London.
In March, 1853, Russia invaded Turkey. Britain and France, concerned about the growing power of Russia, went to Turkey's aid. This conflict became known as the Crimean War. Soon after British soldiers arrived in Turkey, they began going down with cholera and malaria.
Nightingale found the conditions in the army hospital in Scutari appalling. The men were kept in rooms without blankets or decent food. Unwashed, they were still wearing their army uniforms that were "stiff with dirt and gore". In these conditions, it was not surprising that in army hospitals, war wounds only accounted for one death in six. Diseases such as typhus, cholera and dysentery were the main reasons why the death-rate was so high amongst wounded soldiers.
Military officers and doctors objected to Nightingale's views on reforming military hospitals. They interpreted her comments as an attack on their professionalism and she was made to feel unwelcome. Nightingale received very little help from the military until she used her contacts at The Times to report details of the way that the British Army treated its wounded soldiers. John Delane, the editor of newspaper took up her cause, and after a great deal of publicity, Nightingale was given the task of organizing the barracks hospital after the battle of Inkerman and by improving the quality of the sanitation she was able to dramatically reduce the death-rate of her patients
In 1856 Florence Nightingale returned to England as a national heroine. She had been deeply shocked by the lack of hygiene and elementary care that the men received in the British Army. Nightingale therefore decided to begin a campaign to improve the quality of of nursing in military hospitals. In October, 1856, she had a long interview with Queen Victoria and Prince Albert and the following year gave evidence to the 1857 Sanitary Commission. This eventually resulted in the formation of the Army Medical College.
In later life Florence Nightingale suffered from poor health and in 1895 went blind. Soon afterwards, the loss of other faculties meant she had to receive full-time nursing. Although a complete invalid she lived another fifteen years before her death in London on 13th August, 1910.
