UW-Madison geneticist Joshua Lederberg won a Nobel Prize in 1958 after showing how bacteria develop resistance to antibiotics and that the bugs can swap genes-even between species.

Understanding Immunity

In the mid-1940s University of Wisconsin geneticist Ray Owen noticed a surprising fact about non-identical cattle twins. Each twin had two kinds of blood cells, its own and those of its twin. In ordinary transfusions, such mixing of blood cells often leads to severe immunological reaction. Owen realized that when bloods are exchanged early in development, each twin somehow learns to tolerate the other's cells. This discovery of "immune tolerance" helped to explain how an organism can tell its own cells from foreign ones, and fueled a revolution in immunology. The nature of immune tolerance is central to studies of organ transplantation, cancer, and autoimmune diseases.
