Reparations flow the wrong way: What the right doesn’t understand about slavery - Salon.com: 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 R�deur, 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.
