Florence Nightingale

She was born in 1820 in the Italian city of Florence, and her parents did something eccentric: they named her after it. The Nightingales were wealthy, well connected and thoroughly English, and they lived a life of country houses, dinner parties and calling cards. Florence and her elder sister grew up inside a world with a very clear script: a daughter of such a family was expected to be charming in company, to marry a suitable man, and then to run a large household with grace. Her father, unusually for the time, taught his daughters himself — languages, history, philosophy and, crucially, mathematics. He almost certainly intended it as an ornament rather than a weapon. Florence took to figures with an appetite nobody in the family quite understood. Long before she knew what to do with the talent, she was compiling tables of her own — lists, numbers, comparisons — for the pleasure of turning a mess into a pattern. It was the least fashionable accomplishment a young Victorian woman could possess.

From her teens she felt something the family found far harder to accept: a vocation. She believed, and recorded privately, that she was called to serve others, and by her twenties she knew what that service was to be. She wanted to nurse. It is hard now to convey how shocking that sounded in the 1840s. Nursing was not then a profession at all: no training, no qualifications, almost no status. Hospitals were largely places where the poor went to die, and the women who worked in them were widely assumed to be drunken, ignorant, or worse. For a gentleman's daughter to announce that she would spend her life in such wards was, to her mother and sister, close to a public disgrace. The result was years of sullen, exhausting domestic conflict, conducted over breakfast tables and in letters: she was refused permission, sent travelling to distract her, and pressed hard to marry. She did receive a long, serious proposal from a man she genuinely admired, and after years of hesitation she turned him down: marriage, as she saw it, would have swallowed the work whole.

She got her way slowly, by wearing everyone down. In 1851 she was finally allowed to spend several months at Kaiserswerth in Germany, run by Protestant deaconesses, where women were given something like real training in the care of the sick. By the standards she would later set, the instruction was thin. By the standards of her life so far, it was everything: for the first time she was inside a system rather than reading about one. She came home with a plan, and in 1853 she took charge of a small institution in London for sick gentlewomen. She ran it with an attention to detail that startled her committee — plumbing, hot water, supplies, timetables, the mechanics of care. She was thirty-three, at last doing the work, and thoroughly obscure. Then, in 1854, Britain went to war in the Crimea, and a newspaper correspondent began sending home reports that would change her life and a great deal else.

The Crimean War was, in one respect, the first modern war: it was reported. William Howard Russell, writing for The Times, sent back despatches describing what was really happening to British soldiers — not the glory, but the wounded lying untended, the missing supplies, the sheer administrative negligence of the system meant to keep an army alive. The reaction was immediate and furious. Among those under pressure was Sidney Herbert, the Secretary at War, who happened to be a friend of the Nightingale family and knew exactly what Florence had been training for. Late in 1854 he asked her to take a party of nurses to the East, and she went with thirty-eight of them. The appointment was extraordinary in itself: an unmarried gentlewoman, given official authority, sailing towards a war. They were sent to the barrack hospital at Scutari, on the Asian shore opposite Constantinople, a vast converted building to which the sick and wounded were shipped across the Black Sea. What she found there has become one of the most famous scenes in British history, and it was worse than the reports had suggested.

The hospital was overwhelmed. Men lay in corridors on straw, in their uniforms, in squalor. There was no functioning sanitation: the building stood over defective sewers, the water was contaminated, and the wards were dark, damp and crowded, with inadequate ventilation and vermin everywhere. Food arrived late and unfit; bandages, basins, shirts, soap and beds simply were not there, because the supply system had collapsed into a maze of forms that nobody would cut through. Far more soldiers died of disease than of wounds — typhus, cholera and dysentery moved through the wards faster than any Russian gun. Nightingale set to work on what could be organised: kitchens, laundry, stores, records, letters home for the dying. She bought supplies with money raised by The Times, and fought officials who resented her. And at night, when the surgeons had gone, she walked the wards with a lamp, checking on men nobody had ever checked on before. Russell's readers seized on that image, and a poem by Longfellow soon fixed it forever: the Lady with the Lamp.

Here the story usually stops, and here honesty has to begin. Mortality at Scutari did not fall when Nightingale arrived. It stayed appalling, and through her first winter it rose — the hospital was one of the deadliest places a wounded British soldier could be sent. The decisive change came from elsewhere. In March 1855 a Sanitary Commission sent out from London arrived and did the unglamorous work: it flushed the sewers, removed the filth from beneath the building, whitewashed the walls and improved the ventilation. After that the death rate fell dramatically. The credit for that fall belongs largely to plumbing. What matters — and what makes Nightingale interesting rather than merely saintly — is that she came to understand this herself. She went out believing that care and order saved men; she came back with a colder and more useful conviction: that dirt, bad air and bad water were killing them by the thousand, and that this could be proved. She had the figures, and everything she did for the next fifty years grew out of that.

She came home in 1856 to a fame she had not sought and did not enjoy, refusing the public welcome planned for her. Then she did something far more interesting than accepting it: she spent it. For the rest of her life she treated her celebrity as a political instrument, aimed directly at the War Office. She lobbied ministers, wrote to them at exhausting length, and made it plain that the most admired woman in Britain believed the army was killing its own soldiers through neglect. In 1857 a royal commission was appointed to examine the health of the army, with Sidney Herbert at its head; Nightingale, who as a woman could not sit on it, drove it from outside. She compiled the evidence herself. Working through returns and hospital records, she assembled a rigorous statistical account of how British soldiers had died in the East, and produced a vast confidential report of her own. In peacetime barracks as well as in war, men were dying at rates far above those of the civilians around them, and the cause was preventable: bad water, bad drains, overcrowding, bad air.

The difficulty was making ministers see it. Columns of figures can be politely ignored; Nightingale wanted an argument that could not be waved away. So she drew it. Working with the statistician William Farr and others, she presented mortality in vivid diagrams, the most famous being the polar-area chart now usually called her "rose" — a circle of monthly wedges whose areas show the scale of the deaths, shaded to separate deaths from wounds from deaths from preventable disease. The disease sections dwarf the rest. Anyone could see in two seconds what a table would have taken an hour to explain. It was one of the earliest deliberate uses of a picture of data as a political weapon, and it worked. In 1858 she became the first woman elected to the Royal Statistical Society. Sanitary commissions were set up, barracks rebuilt, army medical statistics reorganised; and she pressed the same case for India, where she never travelled but on whose sanitation she advised for decades.

The rest of the legacy is easier to see. She published Notes on Nursing in 1859, written as much for households as for hospitals, and in 1860 the Nightingale training school opened at St Thomas' Hospital, turning nursing from an unregulated occupation into a trained profession with standards, examinations and a career. She advised on hospital design — light, space, air — and shaped wards for a century. She did all of it from a sofa. From soon after her return she was largely bedridden, disabled by an illness widely thought to have been contracted in Crimea, though its nature is still debated; she ran her campaigns by letter from a room in London until she died in 1910, aged ninety. The echoes are everywhere: professional nursing, the idea that public health is built by drains as much as by doctors, and above all the habit of demanding evidence before we believe a treatment works. Whether the lamp has done her a favour is another question. It made her a saint, and saints are easy to admire and easy to ignore. The statistician who beat the establishment with a chart is a more disturbing figure — and a far more useful one.
