Meanwhile, allied countries in the late 1930s and 1940s committed monumental resources to wartime scientific research. In the United States, these efforts were initially led by the National Defense Research Committee. Later, the Office of Scientific Research and Development, organized and administered by the MIT engineer Vannevar Bush, took up the effort of coordinating government efforts in support of science.
