In 1792, а slаve nаmed Henry Mоss began develоping white spоts on his skin and within three years, his body was completely white. A celebrated scientist of the era, [BLANK-1] examined the man and took his condition as confirmation of his belief that the blackness of African Americans derived from leprosy, but that it could be cured. He later published a treatise called Essay on the Causes of the Variety of Complexion and Figure in the Human Species where he argued that changes in the social environment of Black folks could tap into the innate equality of humankind and uplift them – they could be “cured” of their blackness. Proper society, he argued, could gradually whiten African Americans the way that Henry Moss was whitened naturally.
