Rh factor as a cause of hemolytic anemia in newborns

Equipped with the precise tools of modern immunology, and applying these tools with the utmost astuteness, Drs. Landsteiner, Levine, and Wiener discovered the existence in normal human blood of previously unknown hereditary factors which, if not taken properly into account, are capable of causing serious illness or death to unborn and newborn children, and to persons who receive blood transfusions.

The meticulous and successful researches of these scientists have already saved the lives of innumerable human beings—adults and children—and will save the lives of millions yet unborn.
