Vannevar Bush, who is remembered for his work on analog computers and for introducing a concept that we now consider the hyperlink, was born on March 11, 1890 in Everett, Massachusetts, USA.
Like many computer pioneers Vannevar Bush was motivated to build a computer because he needed to solve equations. However, he was already an inventor who had a finely honed instinct for mechanical devices.
While an undergraduate he designed an amazing device that measured ground levels. You rolled it over the terrain and it drew a graph of the change in height. The device was purely mechanical but it included an integrator - the basic component needed to build an analog computer.
March 11, 1890 - June 28, 1974
Starting in 1927, Bush constructed a Differential Analyser, an analog computer that could solve differential equations This was a significant development in the progress towards an analog computer - even though Bush himself disclaimed any credit for the invention of the digital computer.
Bush is also remembered for his proposed Memex machine, a machine that stored and retrieved information using microfilm and used what we would now call a hypertext link to form information trails. So he can be credited with having invented the hyperlink back in 1945.
