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.
Yes, these mulattoes were still considered part of the slave system in the South, but the whites took good care of them, taught them to read and write, treated them as whites, and in few instances, emancipated them and sent them to the North or to the West.
