== Early life and education ==
Vannevar Bush was born in [[Everett, Massachusetts]], on March 11, 1890.<ref>{{Cite book |last= |first= |title=Britannica Concise Encyclopedia |publisher=Encyclopaedia Britannica, Inc. |year=2008 |isbn=978-1-59339-492-9 |pages=301 |language=en}}</ref> He was the third child and only son of Richard Perry Bush, the local [[Christian universalism|Universalist]] pastor, and his wife Emma Linwood (née Paine), the daughter of a prominent Provincetown family.<ref>{{Cite book |last=Zachary |first=G.

He was named after John Vannevar, an old friend of the family who had attended [[Tufts University|Tufts College]] with Perry. The family moved to [[Chelsea, Massachusetts]], in 1892,{{sfn|Zachary|1997|pp=12–13}} and Bush graduated from [[Chelsea High School (Massachusetts)|Chelsea High School]] in 1909.{{sfn|Zachary|1997|p=22}}

Bush graduated from  [[Tufts College]], like his father before him. A popular student, he was vice president of his [[sophomore]] class, and president of his [[Junior (education year)|junior]] class. During his [[Senior (education)|senior]] year, he managed the football team. He became a member of the [[Alpha Tau Omega]] fraternity, and dated Phoebe Clara Davis, who also came from Chelsea. Tufts allowed students to gain a master's degree in four years simultaneously with a [[bachelor's degree]]. For his master's thesis, Bush invented and patented a "profile tracer". This was a mapping device for assisting [[Surveying|surveyors]] that looked like a lawn mower. It had two bicycle wheels, and a pen that plotted the terrain over which it traveled. It was the first of a string of inventions.{{sfn|Zachary|1997|pp=25–27}}<ref>{{cite web |url=http://americanhistory.si.edu/collections/search/object/nmah_1195838 |title=Vannevar Bush's profile tracer |publisher=National Museum of American History |access-date=March 12, 2015}}</ref> On graduation in 1913 he received both Bachelor of Science and Master of Science degrees.{{sfn|Wiesner|1979|pp=90–91}}

After graduation, Bush worked at [[General Electric]] (GE) in [[Schenectady, New York]], for $14 a week.<ref>{{Cite book |last=Zachary |first=G. Pascal |title=Endless Frontier: Vannevar Bush, Engineer of the American Century |publisher=Simon and Schuster |year=2018 |isbn=978-1-5011-9646-1 |pages=28 |language=en}}</ref> As a "test man," he assessed equipment to ensure that it was safe. He transferred to GE's plant in [[Pittsfield, Massachusetts]], to work on high voltage [[transformer]]s, but after a fire broke out at the plant, Bush and the other test men were suspended. He returned to Tufts in October 1914 to teach mathematics, and spent the 1915 summer break working at the [[Brooklyn Navy Yard]] as an electrical inspector.
Bush was awarded a $1,500&nbsp;scholarship to study at [[Clark University]] as a doctoral student of [[Arthur Gordon Webster]], but Webster wanted Bush to study acoustics, a popular field at the time. Bush preferred to quit rather than study a subject that did not interest him.{{sfn|Zachary|1997|pp=28–32}}

Bush subsequently enrolled in the [[Massachusetts Institute of Technology]] (MIT) electrical engineering program. Spurred by the need for enough financial security to marry,{{sfn|Zachary|1997|pp=28–32}} he submitted his thesis, entitled ''Oscillating-Current Circuits: An Extension of the Theory of Generalized Angular Velocities, with Applications to the Coupled Circuit and the Artificial Transmission Line'',{{sfn|Puchta|1996|p=58}} in April 1916. His adviser, [[Arthur Edwin Kennelly]], demanded more work from him, but Bush refused, and Kennelly was overruled by the department chairman. Bush received his doctorate in engineering jointly from MIT and [[Harvard University]].{{sfn|Zachary|1997|pp=28–32}} He married Phoebe in August 1916.{{sfn|Zachary|1997|pp=28–32}} They had two sons: Richard Davis Bush and John Hathaway Bush.{{sfn|Zachary|1997|pp=41, 245}}
