In 1930, Theiler moved to the Rockefeller Foundation in New York, where he later became director of the Virus Laboratory. He was professor of epidemiology and public
First Step to Nobel Prize in Physics the winner was an American student. In 2009, the prize went to Mor Tzaban, a high school student from Netivot, Israel. In 2012, the first prize winner was another Israeli teenager, Yuval Katzenelson of Kiryat Gat, who presented a paper entitled "Kinetic energy of inert gas in a regenerative system of activated carbon."
