Galton’s ideas—most notably in Nazi Germany—have made eugenics a word that produces a shudder of disgust.
Galton’s intellectual pedigree was impeccable. He shared a grandfather, Erasmus Darwin, with his cousin Charles, and the families were closely interknit (two of Francis’s brothers were called Erasmus and Darwin). The Darwins were doctors and scientists; the Galtons were free-thinking Quaker bankers. Both families had produced members of the Royal Society and both helped found the Lunar Society, the influential think tank of industrialists, scientists, and philosophers that included James Watt, Joseph Priestley, and Josiah Wedgwood. Young Francis was an infant prodigy. He learned to read at two and a half and got extra coaching from his older sister Adele, who had a congenital spinal defect that confined her to the house. She proved to be a talented teacher, though her baby brother took most of the credit:
I am four years old and can read any English book. I can say all the Latin Substantives and Adjectives and active verbs besides 52 lines of Latin poetry. I can cast up any sum in addition and multiply by 2, 3, 4, 5, 6, 7, 8, 10. I can also say the pence table. I read French a little and I know the Clock.
This conceitedness, amusingly forgivable in a precocious child, never left Galton. He was clever but socially inept. At the age of five he was sent to a small school in Birmingham. He hated it. “No one had heard of, let alone read,
Galton loved the social life at Cambridge and, much like his cousin Charles, made no great impression there academically. At the end of his fourth year, he suffered a nervous breakdown. He later claimed he had a “sprained brain” from working too hard, but he left with a “pass,” the lowest level of degree awarded. Shortly after this, he was dealt a further blow by the death of his father. But like Humboldt and Mary Kingsley, once the initial grief passed, he realized he was free. What’s more, he discovered he was extremely rich. And like Humboldt and Mary Kingsley, he decided to travel.
He made his first foray to Egypt and the Sudan, crossing the Nubian Desert by camel and learning Arabic. While sailing down the Nile at night, a shore party set off to shoot a hippo, but mistaking their target in the dark, they bagged a cow that had come down to the water’s edge to drink. They had to leave in a hurry. Nor did Dalton make it to his intended destination—the Holy Land. In Damascus his faithful servant Ali died of violent dysentery. Again, Dalton had to make tracks, pursued by a horde of Ali’s “grieving relatives” with threats of legal action (or worse). He arrived back in London with two monkeys, a bad case of gonorrhea contracted from a prostitute, and a strong desire to improve his marksmanship. The monkeys perished when a friend’s landlady left them in a cold scullery overnight, but the venereal disease was treated successfully, and Galton spent a good deal of the next three years teaching himself to shoot on various Scottish estates. By 1850 he was ready to risk the tropics again. He bought a papier-mache crown in Drury Lane, announced his intention to place it on the head of “the greatest or most distant potentate I should meet with,” and set off to unmapped South West Africa. His thousand-mile accident-prone journey produced two very successful books. The first,
In South West Africa, Galton developed the fixation for statistics that would become his lifelong trademark. Adopting the motto “Whenever you can, count,” he fastidiously measured everything he came across: horses, cats, plants, human head shapes, portraits, reaction times. He surveyed the heights of mountains by climbing them and boiling kettles at regular intervals to ascertain their altitude, and he devised a method for measuring the size of African women’s breasts and buttocks by using a sextant. When he finally reached his goal, placing his paper crown on the head of the immensely fat King Nangoro, chief of the Ovambo in northern Namibia, he passed up the chance to verify his instrumental readings at first hand. The chief offered him, by way of thanks, “temporary marriage” to his daughter. When the girl arrived in his tent, naked, smeared with red ochre and butter, Galton ejected her “with scant ceremony.” He had no intention of letting her spoil his white linen suit.
His compulsion for measurement continued on his return to England. He kept a homemade pin-and-paper device in his pocket allowing him to record data unobtrusively. A trip around the country notating the frequency of attractive women led to his publication of a “beauty map” of Britain, stating that London, proportionally speaking, had the most beauties and Aberdeen the highest concentration of the “repellent.” At one rather dreary meeting at the Royal Geographical Society he created a “boredom” chart, logging the total number of fidgets per minute. He mapped optimists and pessimists, people with blond hair and blue eyes, and scoured international court cases to come up with his “honesty” index. Britain (naturally) came out on top, while Greece was “the center of gravity for lying.” He “proved” that prayer was ineffective by noting the average ages of the British royal family (for whom, in those days, every congregation in the country dutifully prayed each Sunday) and demonstrating that they lived no longer than anyone else. He even developed a mathematical formula for a perfect cup of tea, designing and building his own thermometer to test it. (The water, according to Galton, should be 82–87 °C and sit on the leaves for precisely eight minutes—the result will be “full bodied, full tasted, and in no way bitter or flat.”)
In more than three hundred books and articles, Galton alternated between serious scientist and mad expert. For every Gumption-Reviver Machine (a mobile dripping tap positioned above the head to keep students alert) there were genuine scientific insights. His pioneering work in meteorology produced the first working weather map. His “anthropometric laboratory,” based in the South Kensington Museum in London, collated the measurements of almost ten thousand human bodies, revealing for the first time that fingerprints were unique and invariable throughout a person’s life.

Galton had always had a knack of seeing patterns in pages of dull numerical data that eluded other people. His cousin’s publication of
