- People in Computing
- Charles Babbage
- a problem
solver, engineer and inventor
who lived during the
18th
century
- He manufactured an Analytical Engine
- He met Ada Lovelace when she was seventeen
- Logical thought is the formal processes used in thinking and reasoning; it is what most of us use to answer questions as human nature

- famous for designing the first ever computing machine which ran on steam
- he worked out the steps needed to create the numbers on a dial, as well as using cogs to shift the numbers; concluding in a mathematical result that was accurate

- a problem
solver, engineer and inventor
who lived during the
18th
century
- Ada Lovelace
- was
alive during the 19th century and worked as a mathematician and writer
- died at the young age of 36 due to Uterine cancer
- she is considered by many as the “first computer programmer”.
- at 17 years-old, she met Charles Babbage

- she wrote the world's first machine algorithm for an early computing machine, of which existed only on paper
- She is well known for her work on Charles Babbage's proposed mechanical general-purpose computer, the Analytical Engine

- was
alive during the 19th century and worked as a mathematician and writer
- George Boole
- a mathematician who lived in the 19th century
- thought of how humane thinking and logic could be translated into mathematical terms which could later lead to computing
- The three logic gates
are used to decrypt messages by use of 1 and 0
- An AND gate takes two inputs to produce a single output. To get “1”, both inputs must also be 1
- An OR gate is the same; however, a 1 MUST be present in order to output “1”.
- The NOT gate produces an output which is the opposite of the input.

- Alan Turing
- an
English computer
scientist and mathematician, who was alive
during the 20th century
- Turing invented a machine, which worked via the inter-wiring of rotors
- After later analysis, it was believed to be that his cause of death was through cyanide poisoning.
- He suffered cruel treatment from the mostly homophobic British authorities

- He played a crucial role in deciphering the German “Enigma” codes which were very confusing
- Thanks to his machine and invention (the Bombe) the British could pin-point the way the Enigma was set up, simply by feeding the message into the machine
