Austrian-born American physician who showed that leukemia could be caused by a virus. After his first discovery in 1951 of an RNA leukemia virus in mice, the subsequent studies by Gross revealed much about the mode of action of his RNA virus, including the vertical transmission of virus from one generation to the next, the activation of viruses by radiation, and the role of immunity in protection against the agent. His work led other researchers to study the role of viruses in cancer.
