Photograph of Zoltan Ovary, MD (1907-2005), who organized the dinner meeting at which Pathology Department Chairman Chandler Stetson invited Michael Heidelberger, the father of immuno-chemistry, to work at NYU. Ovary and Heidelberger are shown here with Zoltan's students Robert Tigelaar (L), who became a professor of Yale and Domenico Mancino (R), who became director of the University of Naples. Dr. Ovary became a member of the New York University School of Medicine faculty in 1959.

Photograph of Zoltan Ovary, MD (1907-2005) demonstrating one of his key contributions to immunology, the Passive Cutaneous Anaphylaxis (PCA) reaction, in the 1960s. Dr. Ovary became a member of the New York University School of Medicine faculty in 1959. While at NYU, working with Baruj Benacerraf and others, he discovered the “carrier-effect,” i.e., the same carrier protein for the foreign substance must be used in subsequent immunizations to produce the maximum number of antibodies; and the once controversial, but for now fundamental concept that there are different classes of antibodies with different biological properties.
