"In 1950 and 1951, Drs. Cowen and Wolf published a series of 5 papers, super-titled, “Experimental Congenital Toxoplasmosis,” in which they demonstrated the intrauterine infection of placenta, fetus, and offspring with Toxoplasma, following its administration to pregnant mice intravaginally. They also elucidated the mechanism of disease transmission and the manifestations of toxoplasmosis in the mothers and in the products of their pregnancies, among other subjects. These investigations, which included the first histological demonstration of toxoplasmosis in the placenta of any species, together with the case reports that came before, brought them international recognition" (Geller, "In Memoriam," J. Neuropath & Exp. Neurol,. 62, 587-89).
