Many in the United States were outraged by the remarks of conservative evangelical preacher Pat Robertson, who blamed Haiti's catastrophic 2010 earthquake on Haitians for selling their souls to Satan. Bodies were still being pulled from the rubble—as many as 300,000 died—when Robertson went on TV and gave his viewing audience a little history lesson: the Haitians had been "under the heel of the French" but they "got together and swore a pact to the devil. They said, 'We will serve you if you will get us free from the French.' True story. And so, the devil said, 'OK, it's a deal.'"
A supremely callous example of right-wing idiocy? Absolutely. Yet in his own kooky way, Robertson was also onto something. Haitians did, in fact, swear a pact with the devil for their freedom. Only Beelzebub arrived smelling not of sulfur, but of Parisian cologne.
Haitian slaves began to throw off the "heel of the French" in 1791, when they rose up and, after bitter years of fighting, eventually declared themselves free. Their French masters, however, refused to accept Haitian independence. The island, after all, had been an extremely profitable sugar producer, and so Paris offered Haiti a choice: compensate slave owners for lost property—their slaves (that is, themselves)—or face its imperial wrath. The fledgling nation was forced to finance this payout with usurious loans from French banks. As late as 1940, 80 percent of the government budget was still going to service this debt.
In the on-again, off-again debate that has taken place in the United States over the years about paying reparations for slavery, opponents of the idea insist that there is no precedent for such a proposal. But there is. It's just that what was being paid was reparations-in-reverse, which has a venerable pedigree. After the War of 1812 between Great Britain and the US, London reimbursed southern planters more than a million dollars for having encouraged their slaves to run away in wartime. Within the United Kingdom, the British government also paid a small fortune to British slave owners, including the ancestors of Britain's current Prime Minister, David Cameron, to compensate for abolition (which Adam Hochschild calculated in his 2005 book Bury the Chains to be "an amount equal to roughly 40 percent of the national budget then, and to about $2.2 billion today").
Advocates of reparations—made to the descendants of enslaved peoples, not to their owners—tend to calculate the amount due based on the negative impact of slavery. They want to redress either unpaid wages during the slave period or injustices that took place after formal abolition (including debt servitude and exclusion from the benefits extended to the white working class by the New Deal). According to one estimate, for instance, 222,505,049 hours of forced labor were performed by slaves between 1619 and 1865, when slavery was ended. Compounded at interest and calculated in today's currency, this adds up to trillions of dollars.
But back pay is, in reality, the least of it. The modern world owes its very existence to slavery.
Voyage of the Blind
Consider, for example, the way the advancement of medical knowledge was paid for with the lives of slaves.
The death rate on the trans-Atlantic voyage to the New World was staggeringly high. Slave ships, however, were more than floating tombs. They were floating laboratories, offering researchers a chance to examine the course of diseases in fairly controlled, quarantined environments. Doctors and medical researchers could take advantage of high mortality rates to identify a bewildering number of symptoms, classify them into diseases, and hypothesize about their causes.
Corps of doctors tended to slave ports up and down the Atlantic seaboard. Some of them were committed to relieving suffering; others were simply looking for ways to make the slave system more profitable. In either case, they identified types of fevers, learned how to decrease mortality and increase fertility, experimented with how much water was needed for optimum numbers of slaves to survive on a diet of salted fish and beef jerky, and identified the best ratio of caloric intake to labor hours. Priceless epidemiological information on a range of diseases—malaria, smallpox, yellow fever, dysentery, typhoid, cholera, and so on—was gleaned from the bodies of the dying and the dead.
When slaves couldn't be kept alive, their autopsied bodies still provided useful information. Of course, as the writer Harriet Washington has demonstrated in her stunning Medical Apartheid, such experimentation continued long after slavery ended: in the 1940s, one doctor said that the "future of the Negro lies more in the research laboratory than in the schools." As late as the 1960s, another researcher, reminiscing in a speech given at Tulane Medical School, said that it was "cheaper to use Niggers than cats because they were everywhere and cheap experimental animals."
Medical knowledge slowly filtered out of the slave industry into broader communities, since slavers made no proprietary claims on the techniques or data that came from treating their slaves. For instance, an epidemic of blindness that broke out in 1819 on the French slaver Rôdeur, which had sailed from Bonny Island in the Niger Delta with about 72 slaves on board, helped eye doctors identify the causes, patterns, and symptoms of what is today known as trachoma.
The disease first appeared on the Rôdeur not long after it set sail, initially in the hold among the slaves and then on deck. In the end, it blinded all the voyagers except one member of the crew. According to a passenger's account, sightless sailors worked under the direction of that single man "like machines" tied to the captain with a thick rope. "We were blind—stone blind, drifting like a wreck upon the ocean," he recalled. Some of the sailors went mad and tried to drink themselves to death. Others retired to their hammocks, immobilized. Each "lived in a little dark world of his own, peopled by shadows and phantasms. We did not see the ship, nor the heavens, nor the sea, nor the faces of our comrades."
But they could still hear the cries of the blinded slaves in the hold.
This went on for 10 days, through storms and calms, until the voyagers heard the sound of another ship. The Spanish slaver San León had drifted alongside the Rôdeur. But the entire crew and all the slaves of that ship, too, had been blinded. When the sailors of each vessel realized this "horrible coincidence," they fell into a silence "like that of death." Eventually, the San León drifted away and was never heard from again.
The Rôdeur's one seeing mate managed to pilot the ship to Guadeloupe, an island in the Caribbean. By now, a few of the crew, including the captain, had regained some of their vision. But 39 of the Africans hadn't. So before entering the harbor the captain decided to drown them, tying weights to their legs and throwing them overboard. The ship was insured and their loss would be covered: the practice of insuring slaves and slave ships meant that slavers weighed the benefits of a dead slave versus living labor and acted accordingly.
Events on the Rôdeur caught the attention of Sébastien Guillié, chief of medicine at Paris's Royal Institute for Blind Youth. He wrote up his findings—which included a discussion of the disease's symptoms, the manner in which it spread, and best treatment options—and published them in Bibliothèque Ophtalmologique, which was then cited in other medical journals as well as in an 1846 US textbook, A Manual of the Diseases of the Eye.
Slaves spurred forward medicine in other ways, too. Africans, for instance, were the primary victims of smallpox in the New World and were also indispensable to its eradication. In the early 1800s, Spain ordered that all its American subjects be vaccinated against the disease, but didn't provide enough money to carry out such an ambitious campaign. So doctors turned to the one institution that already reached across the far-flung Spanish Empire: slavery. They transported the live smallpox vaccine in the arms of Africans being moved along slave routes as cargo from one city to another to be sold: doctors chose one slave from a consignment, made a small incision in his or her arm, and inserted the vaccine (a mixture of lymph and pus containing the cowpox virus). A few days after the slaves set out on their journey, pustules would appear in the arm where the incision had been made, providing the material to perform the procedure on yet another slave in the lot—and then another and another until the consignment reached its destination. Thus the smallpox vaccine was disseminated through Spanish America, saving countless lives.
