Vannevar Bush was an American engineer and inventor who was head of the US Office of Scientific Research and Development during World War II. In this role he oversaw all of the military research and development, coordinating the activities of large numbers of scientists, engineers, and thinkers of his time to build weapons of war, including the Manhattan Project.
Before the war the scientists and engineers were often in competition with each other for new discoveries, or they were willing to collaborate but unable to find out about each other’s work and learn from other people’s ideas.
Because of the war, many people came together to work towards a common goal, leading to rapid advancements in many fields. Vannevar would have certainly realized the value of the increased collaboration and how much more can be accomplished when the previous barriers were removed.
In 1945, the War was coming to a close. In his essay As We May Think, Vannevar expressed his concerns that the productivity of the scientific and engineering communities would decline as the pre-war barriers returned. He wanted to see the collaboration continue, but for the betterment of humankind, not the pursuit of destruction.
