In the United States, the foundation for post-WWII science policy was laid out in Vannevar Bush's Science – the Endless Frontier, submitted to President Truman in 1945. Vannevar Bush was President Roosevelt's science advisor and became one of the most influential science advisors as in his essay, he pioneered how we decide on science policy today.[12] Vannevar Bush, director of the office of scientific research and development for the U.S. government, wrote in July 1945 that "science is a proper concern of government" [13] This report led to the creation of the National Science Foundation in 1950 to support civilian scientific research.
