teaching ... and that fair balance must be achieved." He decided he was much more interested "guiding research and advanced degree students than in the tiresome details of undergraduate instruction." M. Parker Givens, a Cornell Ph.D, joined the Institute during this growth spurt. This permitted an increase in students. "Fourteen, he said, should be graduating, in 1948, and the total student enrollment was 53, about equally divided through the classes." One of the hallmark innovations developed following the war was a camera with a six-inch f/1 lens for night aerial work, "giving excellent definition over a curved surface, the film being curved by compressed air between the lens and film." Another, first described at a meeting of the Society of Motion Picture Engineers in 1949, was a high-speed camera, "used for observations at the Bikini bomb test, later much improved to make rapid sequences of pictures at speeds up to 20 million frames per second." O'Brien was elected to both the American Philosophical Society and the American Academy of Arts and Sciences in 1953, and the United States National Academy of Sciences in 1954.
