Who invented Rhogam in 1963?

Rhogam was developed by Dr. Karl Landsteiner and Dr. Alexander Solomon in the early 1960s. Their work led to the creation of Rho(D) immune globulin, which is used to prevent Rh immunization in Rh-negative pregnant women. The introduction of Rhogam in 1963 significantly reduced the incidence of hemolytic disease of the newborn.
