In 1943, Horstmann and Tatlock reported detecting cold agglutinins in the serum of patients with primary atypical pneumonia. Fifty years after Landsteinerâs findings, the term âcold agglutinin diseaseâ was coined by Schubothe.
Mulattoes were the direct offspring of plantation rapes. Slave masters often threat the female slaves if they resist the masterâs desire of having intercourse. If they fought back, the female slaves will be whipped, will be beaten up, or worse of all, will be killed.
Lydia Maria Child introduced the literary character that we call the tragic mulatto1 in two short stories: The Quadroons (1842) and Slavery's Pleasant Homes (1843). She portrayed this light skinned woman as the offspring of a white slaveholder and his black female slave. This mulatto's life was indeed tragic.
