Charles Babbage & Alan Turing

Final Draft

Charles Babbage

 

 

Charles Babbage was born in London on December 26, 1792. He was the son of

 

 

Benjamin Babbage, a London banker. As a youth Babbage was his own instructor in Algebra.

 

 

Upon entering Trinity College, Cambridge in 1811, he found himself far in advance of his

 

 

tutors.

 

 

Babbage founded the Analytical Society for promoting continental mathematics

 

 

and reforming the mathematics of Newton then taught at the university. He was elected a

 

 

Fellow of the Royal Society. He played an important role in the establishment of the Association

 

 

for the Advancement of Science and the Statistical Society. Babbage acquired the interest in

 

 

calculating machinery that became his consuming passion for his life.

 

 

His published works are A Comparative View of the Various Institutions for the

 

 

Assurance of lives (1826), Table of Logarithms of the Natural Numbers from 1 to 108,000

 

 

(1827), Reflections on the Decline of Science in England (1830), On the Economy of Machinery

 

 

and Manufacturers (1832), Ninth Bridgewater Treatise(1837), and the autobiographical

 

 

Passages from the life of a Philosopher (1864).

 

 

 

He is admired by computerists because he was the first person to realize that a

 

 

computing machine must be composed of an input device, a memory, a central processing unit,

 

 

and an output device. Babbage calculated the first reliable mortality tables. He also worked out

 

 

the first speedometer, invented the locomotive "cow catcher" and built a device to study the

 

 

retina of the eye.

 

 

He is often referred as the "Father of Computing" because of his inventions of the

 

 

analytical engine, and he is also known as the "Grandfather of Modern Digital Computing". The

 

 

Charles Babbage Foundation took his name to honor his intellectual contributions and their

 

 

relation to modern computers.

 

 

Despite his many achievements, the failure to construct his calculating machines

 

 

and in particular the failure of the government to support his work left Babbage in his declining

 

 

years a disappointed and embittered man.

 

 

He died at his home in Dorset Street, London, on October 18, 1871.

 

 

 

Alan Mathison Turing

 

 

Alan Mathison Turing was born in a nursing home in Paddington, London, on

 

 

June 23, 1912. He belonged in an upper-middle class, distinctive English family. His father,

 

 

Julius Mathison Turing was in the Indian Civil Service. Turing had an older brother named John

 

 

who was born in 1908. His father died in 1947 and his mother in 1976.

 

 

Turing studied at Sherbone School. Then he studied relativity, quantum

 

mechanics, probability and logic at King’s College, Cambridge University, Princeton University

 

 

and at Manchester University.

 

 

He is known as the "Founder of Computer Science" because he helped design the

 

 

first computer and developed early computer that cracked military codes. He helped to crack

 

 

German military codes and win World War II against Hitler. Turing who was a strange man,

 

 

one who never fitted in anywhere quite successfully, was a mathematician, philosopher, code

 

 

breaker and a gay man.

 

 

He died on June 7, 1954 by cyanide poisoning in Wilmslow, Cheschire.
