Myth #1: Joseph-Marie Jacquard invented the punched card
• On 23 Dec. 1800, he registered a patent for a machine “designed to replace the draw-boy in the manufacture of figured fabrics”.
• Jacques de Vaucanson is credited with creating the world's first true robots, as well as creating the first completely automated loom (1740).
• In 1728, Jean Falcon built a loom that used punched cards• In 1725, Basile Bouchon invented a way to control a loom
with a perforated paper tape. The son of an organ maker, he adapted the concept of music automata controlled by pegged cylinders to the repetitive task of weaving.

• By 1834, he had received £17,470 (enough to build two battleships) to build the Difference Engine, but starting to design the Analytical Engine
• By 1834, he had started work on the Analytical Engine (using punched cards to store data and instructions was able to perform calculations automatically)
• Told Sir Robert Peel that he had stopped work on the Difference Engine so that he could build the Analytical Engine

• On two occasions I have been asked, – "Pray, Mr. Babbage," if you put into the machine wrong figures, will the right "answers come out?" In one case a member of the Upper, and in the other a member of the Lower, House put this question. I am not able rightly to apprehend the kind of confusion of ideas that could provoke such a question.

Charles Babbage – Father of ComputingCharles Babbage – Father of Computing• Counted all the broken panes of glass of a factory,
publishing in 1857 a "Table of the Relative Frequency of the Causes of Breakage of Plate Glass Windows": 14 of 464 were caused by "drunken men, women or boys".
• His distaste for commoners ("the Mob") included writing "Observations of Street Nuisances" in 1864, as well as tallying up 165 "nuisances" over a period of 80 days; he especially hated street music.
• Obsessed with fire, once baking himself in an oven at 265°F (130°C) for four minutes "without any great discomfort" to "see what would happen."
• Later, he arranged to be lowered into Mount Vesuvius in order to view molten lava for himself.

• If the Analytical Engine had been built, it would have been in many ways more advanced than some of the first computers that emerged in the 1940s. It would have been digital, programmable and Turing complete.
• However, it would have been very slow. Ada Lovelace reported in her notes on the Analytical engine: "Mr. Babbage believes he can, by his engine, form the product of two numbers, each containing twenty figures, in three minutes".
• By comparison the Harvard Mark I could perform the same task in just six seconds. A modern PC can do the same thing in well under a billionth of a second.

weaves flowers and leaves.”
