    1. The Electro-Mechanical Period By: Justice Montina, Ericka Martinez, and Mary Brown

    2. Main Points • In this presentation we will discuss • The electro-mechanical period • What machines it had • How they were made • What was happening in this time

    3. What Was happening at this time??? • World war • different plans for child health was going on • there was invasions in the time of 1910

    4. Vannevar Bush’s analog computer • Vannevar Bush was never directly involved with the creation or development of the Internet. He died before the creation of the World Wide Web. Yet many consider Bush to be the Godfather of our wired age often making reference to his 1945 essay, "As We May Think." In his article, Bush described a theoretical machine he called a "meme," which was to enhance human memory by allowing the user to store and retrieve documents linked by associations. This associative linking was very similar to what is known today as hypertext. Indeed, Ted Nelson who later did pioneering work with hypertext credited Bush as his main influence . Others, such as J.C.R. Likelier and Douglas Engelhard have also paid homage to Bush.

    5. Aiken’s Digital Computer • The desire for answers to the questions raised by his doctoral thesis in physics led Howard Aiken to the conclusion that he would have to build a calculating machine unlike anything ever seen before at Harvard -- a computer. • Aiken needed numbers for his theory of space-charge conduction in vacuum tubes, but the problems were beyond the capability of desktop calculators of the day. Frustrated by his dilemma, in 1937 he wrote a proposal for a giant calculating machine, one that could represent negative and positive numbers, do standard arithmetic, and carry out more than one operation in a sequence.

    6. Herman Hollerith’s Electronic Tabulating Machine • Herman Hollerith, American inventor, born in Buffalo, New York, and educated at Columbia University, who devised a system of encoding data on cards through a series of punched holes. This system proved useful in statistical work and was important in the development of the digital computer. Hollerith's machine, used in the 1890 U.S. census, "read" the cards by passing them through electrical contacts. Closed circuits, which indicated hole positions, could then be selected and counted. His Tabulating Machine Company (1896) was a predecessor to the International Business Machines Corporation.

    7. International Business Machines

    8. History • During this period of time so many things happened like the finding-outs of technology and the finding of us using electrical this to run out hand make objects. Because of then,, with them making new accomplishments we the new generation will be able to build off of their findings. • Then • And Now

    9. What Have We Learned? • We have Accomplished so much scene the 19’10s! We have went from just trying to get energy to flow, to now having I-pods, Computers and Cell-Phone. We have come from along way. Just think of what will happened in the future!
