A Short History of Computing
A Short History of Computing 01/15/15 1 Jacques de Vaucanson 1709-1782 • Gifted French artist and inventor • Son of a glove-maker, aspired to be a clock- maker • 1727-1743 – Created a series of mechanical automations that simulated life. • Best remembered is the “Digesting Duck”, which had over 400 parts. • Also worked to automate looms, creating the first automated loom in 1745. 01/15/15 2 1805 - Jacquard Loom • First fully automated and programmable loom • Used punch cards to “program” the pattern to be woven into cloth 01/15/15 3 Charles Babbage 1791-1871 • English mathematician, engineer, philosopher and inventor. • Originated the concept of the programmable computer, and designed one. • Could also be a Jerk. 01/15/15 4 1822 – Difference Engine Numerical tables were constructed by hand using large numbers of human “computers” (one who computes). Annoyed by the many human errors this produced, Charles Babbage designed a “difference engine” that could calculate values of polynomial functions. It was never completed, although much work was done and money spent. Book Recommendation: The Difference Engine: Charles Babbage and the Quest to Build the First Computer by Doron Swade 01/15/15 5 1837 – Analytical Engine Charles Babbage first described a general purpose analytical engine in 1837, but worked on the design until his death in 1871. It was never built due to lack of manufacturing precision. As designed, it would have been programmed using punch-cards and would have included features such as sequential control, loops, conditionals and branching. If constructed, it would have been the first “computer” as we think of them today. -
