This is a photograph of Francis Peyton Rous. He lived from 1879-1970. From 1909 to 1911, he made two innovative discoveries that are now the foundation blocks of modern virology and oncology. First he discovered that a malignant tumor (a sarcoma in chickens) transmissible; it was the first transmissible solid tumor discovered. Secondly, he found that the tumor-inducing factor could be passed through a Berkefeld ultrafilter known to retain bacteria.

She persevered in supporting his education because in 1900 and 1905 respectively, he received his Bachelor of Arts and doctoral degrees from the Johns Hopkins University in Baltimore. Soon after teaching pathology at the University of Michigan, Ann Arbor, and studying morbid anatomy at Freidrichsadt Municipal Hospital in Dresden Germany in 1909, he took a position at the Rockefeller Institute of Medical Research in New York, New York. He spent the rest of his life working there. The institute at which he worked, was the first place in the United States where virology first surfaced as a distinct medical science. From the beginning of his medical career, he was surrounded by great minds. Rous’ entry into tumor virology was accidental but fortunate. The founding director of the Rockefeller Institute, Simon Flexner, had been interested
