Albert Einstein and J. Robert Oppenheimer were twentieth century physicists who made pioneering contributions to physics. From 1947 to 1955 they had been colleagues at the Institute for Advanced Study (IAS). Belonging to different generations, Einstein and Oppenheimer became representative figures for the relationship between "science and power", as well as for "contemplation and utility" in science. The Institute for Advanced Study (IAS) is an independent center for theoretical research and intellectual inquiry located in Princeton, New Jersey. It has served as the academic home of internationally preeminent scholars, including Albert Einstein, J. Robert Oppenheimer, Hermann Weyl, John von Neumann, Michael Walzer, Clifford Geertz and Kurt Gödel, many of whom had emigrated from Europe to the United States. It was founded in 1930 by American educator Abraham Flexner, together with philanthropists Louis Bamberger and Caroline Bamberger Fuld. Despite collaborative ties and neighboring geographic location, the institute, being independent, has "no formal links" with Princeton University. The institute does not charge tuition or fees. Alfred Eisenstaedt (December 6, 1898 – August 23, 1995) was a German-born American photographer and photojournalist. He began his career in Germany prior to World War II but achieved prominence as a staff photographer for Life magazine after moving to the U.S. Life featured more than 90 of his pictures on its covers, and more than 2,500 of his photo stories were published. Among his most famous cover photographs was V-J Day in Times Square, taken during the V-J Day celebration in New York City, showing an American sailor kissing a nurse in a "dancelike dip" which "summed up the euphoria many Americans felt as the war came to a close", in the words of his obituary. He was "renowned for his ability to capture memorable images of important people in the news" and for his candid photographs taken with a small 35mm Leica camera, typically with natural lighting sends by La Poste
