Technical superiority could be a deterrent to future enemy aggression. During July 1945, in his report to the President Science, the Endless Frontier, bush wrote that basic research was: "the pacemaker of technological progress and "New products and new processes do not appear full-grown. They are founded on new principles and new conceptions, which in turn are painstakingly developed by research in the purest realms of science!" he recommended the creation of what would eventually become in 1950 the national Science foundation (NSF). Simultaneously during July 1945, the kilgore bill was introduced in Congress proposing a single science administrator appointed and removable by the President, with emphasis on applied research, and a patent clause favoring a government monopoly. In contrast, the competing Magnuson bill was similar to bush's proposal to vest control in a panel of top scientists and civilian administrators with the executive director appointed by them, to emphasize basic research, and to protect private patent rights. A compromise kilgore-magnuson bill of February 1946 passed the senate but expired in the house because bush favored a competing bill that was a virtual duplicate of the original Magnuson bill.

Roosevelt wrote bush, "I have read your extremely interesting report and i agree that the time has come for a review of the work of the Office on New weapons. I am returning the report for you to lock up, as I think it is probably better that I should not have it in my own files." 7 Bush's method of management at osrd was to direct overall policy while delegating supervision of divisions. He attempted to interpret the mandate of osrd as narrowly as possible to avoid overtaxing his office and to prevent duplicating the efforts of other agencies. Other problems were obtaining adequate funds from the President and Congress and determining apportionment of research among government, academic, and industrial facilities. However, his most difficult problems, and also greatest successes, were keeping the confidence of the military, which distrusted the ability of civilians to observe iron security regulations, and opposing conscription of young scientists from into the armed forces. The new York times in its obituary described him as a master craftsman at steering around obstacles, whether they were technical or political or bull-headed generals and admirals. Conant commented, to see him in action with the generals was an exhibit. Post-war years osrd continued to function actively until some time after the end of hostilities, but by 19 it had been reduced to a minimal staff charged with finishing work remaining from the war period. Bush and many others had hoped that with the dissolution of osrd, an equivalent peacetime government research and development agency would replace. Bush felt that basic research was important national survival for both military and commercial reasons, requiring continued government support for science and technology.

Bush later agreed: "That, in fact, is exactly what it was." This co-ordination of scientific effort was instrumental for the Allies winning the second World War. Alfred loomis (photo above) said that "Of the men whose death in the summer of 1940 would have been the greatest calamity for America, the President is first, and. Bush would be second or third." During 1941 the ndrc was subsumed into the Office of Scientific Research and database development (osrd) with Bush as director, which controlled the manhattan Project until 1943 (when administration was assumed by the Army) and which also coordinated scientific research. In all, osrd directed 30,000 men and oversaw development of some 200 weapons and instrumentalities of war, including sonar, radar, the proximity fuze, amphibious vehicles, and the norden bomb sight, all considered critical in winning the war. At one time, two-thirds of all the nations physicists were working under Bushs direction. In addition, osrd contributed to many advances of the physical sciences and medicine, including the mass production of penicillin and sulfa drugs. Of the war, bush said in " As we may think "This has not been a scientist's war; it has been a war in which all have had a part. The scientists, burying their old professional competition in the demand of a common cause, have shared greatly and learned much." 6 Another good example of the close working relationship between Bush and President roosevelt was in a brief memo, dated March 20, 1942, providing approval.

He managed to get a meeting with the gps President on took a single sheet of paper describing the proposed agency. Roosevelt approved it in ten minutes. Ndrc was functioning, with Bush as chairman and others as members, even before the agency was made official by order of the council of National Defense on June 27, 1940. Bush quickly appointed four leading scientists to nrdc: naca colleagues Conant, compton, and Jewitt, and also richard. Tolman, dean of the graduate gender school at Caltech. Each was assigned an area of responsibility. Compton was in charge of radar, conant of chemistry and explosives, jewitt of armor and ordnance, and Tolman of patents and inventions. Government officials then complained that Bush was attempting to by-pass them and to acquire more authority for himself.

And the need for mobilization for defense, bush in 1939 proposed a general directive agency in the federal government, which he often discussed with his colleagues at naca, james. Conant (President of Harvard University karl. Compton (President. ) (both pictured with Bush in photo right and Frank. Jewitt, President of the national Academy of Sciences. Bush continued to urge for the agency's creation. Early in 1940, at Bush's suggestion, the secretary of naca began preparing a draft of the proposed National Defense research Committee (ndrc) to be presented to congress. But when the germans invaded France, bush decided speed was important and signalled President roosevelt directly.

Smith that greatly improved the efficiency of radios. Bush made much money from the venture. The company, renamed raytheon, became a large electronics company and defense contractor. Starting in 1927, bush constructed a differential Analyser, an analog computer that could solve differential equations with as many as 18 independent variables. An offshoot of the work at mit disadvantages was the beginning of digital circuit design theory by one of Bush's graduate students, Claude Shannon. World War ii period During 1939 Bush accepted a prestigious appointment as president of the carnegie institution of Washington, which awarded large sums annually for research. As president, bush was able to influence research in the.

Towards military objectives and could informally advise the government on scientific matters. During 1939 he became fully involved with politics with his appointment as chairman of National Advisory committee for Aeronautics, which he directed through 1941. Bush remained a member of naca through 1948. During World War i, bush had known business the lack of cooperation between civilian scientists and the military. Concerned about the lack of coordination in scientific research in the.

4 This post included many of the powers and functions subsumed by the Provost when mit introduced this post during 1949 including some appointments of lecturers to specific posts. While at mit, bush urged Col. Harwood to found the American Institute for Economic Research as an independent, scientific research institute. Spurred by the need for enough financial security to marry, bush finished his thesis in less than a year. During August 1916 he married Phoebe davis, whom he had known since tufts, in Chelsea, massachusetts.


He received a doctorate in engineering from mit and Harvard University, jointly, in 1917—after a dispute with his adviser Arthur Edwin Kennelly, who tried to demand more work from Bush. 5 During World War I he worked with the national Research council with about six thousand leading American scientists in the application of science to warfare. Such as developing submarines, trip hammers, and better microscopes. He joined the department of Electrical Engineering at mit in 1919 and was a professor there from 192332. During 1922, bush and his college roommate, laurence. Marshall, set up the American Appliance company to market a device called the s-tube. This was a gaseous rectifier invented.

New Media." 3 Life and work vannevar father's Bush was born in everett, massachusetts, to richard Perry bush and Emma linwood paine. He was educated at Tufts College (now Tufts University graduating in 1913. From mid-1913 to October 1914, bush worked at General Electric (where he was a supervising "test man during the academic year, bush taught mathematics at Jackson College (the partner school of Tufts). After a summer working as an electrical inspector and a brief stint at Clark University as a doctoral student of Arthur Gordon Webster, bush entered the massachusetts Institute of Technology (MIT) electrical engineering program. Bush was vice-president and dean of engineering at mit from 1932 to 1938. In June 1940 he convinced Franklin Delano roosevelt to give him funding and political support to create a new kind of collaborative relationship between military, industry, and academic researchers-without congressional, or nearly any other, oversight.

From wikipedia, the free encyclopedia, vannevar Bush (March 11, 1890 june tony 28, 1974; pronounced /vænivɑr/ van-nee-var ) was an, american engineer and science administrator known for his work on analog computing, his political role in the development of the atomic bomb as a primary organizer. Manhattan, project, and the idea of the memex, an adjustable microfilm-viewer which is somewhat analogous to the structure of the. As Director of the Office of Scientific Research and development, bush has coordinated the activities of some six thousand leading. American scientists in the application of science to warfare. 1, bush was a well-known policymaker and public intellectual during. World War ii and the ensuing, cold War 2, and was in effect the first presidential science advisor. Bush was a proponent of democratic technocracy and of the centrality of technological innovation and entrepreneurship for both economic and geopolitical security.

most) of his grandiose dreams have yet to spring into existence, it was this address - especially his foreshadowing of hypertext - that gave bush his place as a pioneer of the Internet. In 1940, bush became Chairman of the national Defense research Committee. By 1941 he was appointed Director of the new Office of Scientific Research and development, established to co-ordinate weapons research and advise on scientific research and development. Between 19, bush oversaw a number of new scientific developments, including the refinement of radar, mass production of penicillin, and the creation of the first atomic bomb. While working with the Office of Scientific Research and development, bush maintained his presidency of the carnegie institute (which actually paid his wages while he was working with the osrd - nice lurk if you can get it a position he held from. Bush returned to the massachusetts Institute of Technology in 1955, where he stayed until retirement in 1971. Related: Charles Babbage, claude Shannon).

The differential Analyser reviews itself was fascinating, an analogue device that calculated using all ten digits of the decimal system - rather than the two digit binary system later devised by bush's student, Claude Shannon - this thing ran the entire length of a large room. Measuring movement and distance, and calculating according to these measurements, this device used shaft movement to represent variables, gears to multiply and divide, and differential gears to add and subtract. It could calculate no less than 18 independent variables, and integration was achieved via a sharply-edged wheel spinning at variable radius on a round rotating table. This thing was massive, this thing was complex, this thing was built at the hands of men who loved machines. True, it was cumbersome, clumsy, and built at a time when mechanical machines were steadily giving way to electromechanical devices, but to anyone with a spark of poetry in their soul, this was one awe-inspiringly beautiful machine! Unfortunately, when you get right down to it, the differential Analyser really only had one lasting claim to its position as a predecessor to the modern computer - it was while working on its oily innards that Claude Shannon devised his boolean algebra and electrical. Bush himself went on to invent the rapid Selector, a microfilm storage and information retrieval device that he expanded - in theory, anyway - with his plans for the.

History of Computers

"The world has arrived at an age of cheap complex devices of great reliability, and something is write bound to come. Vannevar Bush ( while, george Stibitz and. Konrad Zuse were trying to develop the circuitry that would eventually lead to the invention of the digital computer, vannevar Bush was working at the massachusetts Institute of Technology - but he was heading in a different direction. Bush was attempting to re-invent, charles Babbage 's Difference Engine. He did it, too. At a time when engineers were beginning to look towards electrical circuits for more efficient processing of much more complex operations, bush managed to produce a calculating machine that used electricity only to turn the shafts, which turned the cranks, which clanked away clumsily. Bush's continuous integraph, later called the differential Analyser, was still a significant development in the progress towards an analogue computer, influencing development of analogue machines around the world.
