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.
The noun mulatto is an old-fashioned way to refer to someone with one black parent and one white parent. It was common to describe a mixed race person as a mulatto during the period of slavery in the United States. If you use the word mulatto to describe someone of mixed race, most people will know what you mean, but they may also be offended. People of mixed race are much more likely to describe themselves as biracial than mulatto these days.
