dr. vannevar bush (1940s worked in manhattan project , early stages of development of computer)

Vannevar Bush  was an American engineer, inventor, physicist, and science administrator who was instrumental in swift advance of scientific research and development of weapons during WWII. Born and raised in Massachusetts, he earned his B.S. and M.S. from ‘Tufts University,’ and a doctorate in electrical engineering from ‘MIT’ and ‘Harvard University.’ A pioneer in analog computers, he constructed a ‘differential analyzer’ that could solve equations with as many as 18 independent variables. He theorized a device that could be used to compress and store data. He called it ‘Memex,’ which later proved inspirational for those who worked on hypertext and digital computers. He invented several devices and registered 49 electronic patents. Bush was the scientific advisor to the US President and the Federal government during WWII. He led the ‘National Defense Research Committee (NDRC),’ and then served as director of the ‘Office of Scientific Research and Development’ (OSRD). He was also chairman of the ‘National Advisory Committee for Aeronautics’ (NACA). As chairman of the OSRD and the NDRC, he initiated the crucial ‘Manhattan Project.’ He authored a number of books and is known for his articles ‘As We May Think,’ and ‘Science, the Endless Frontier.’

batch processing ; big computers that can only do one task at a time

douglas engelbert ; computers inspired him, and invented the mouse and many other inventions related to computers

He was the primary force behind the design and development of the multi-user oN-Line System (NLS), featuring original versions of human-computer interface elements including collaborative software, hypertext and precursors to the graphical user interface, such as the computer mouse.

In 1968, Engelbart and his team presented the NLS at a computer conference in a demonstration that quickly became known as “The Mother of All Demos.” In 1969 they became the second host on the ARPAnet, exchanging first transmissions with UCLA.  A year later, Engelbart wrote “Intellectual Implications of Multi-Access Computer Networks,” in which he foretold the emergence of a new “marketplace” representing “fantastic wealth in commodities of knowledge, service, information, processing, and storage,”  with “a vitality and dynamism as much greater than today’s as today’s is greater than the village market.” Engelbart also founded ARPAnet’s Network Information Center.

DARPA; darpa created a network to avoid losing to russia’s developments , cold war time. russia at that time released sputnik to space, US was afraid of losing to them, so they formed networks to be more efficient at their work.
