1900-1939

1900 - 1939
Konrad Zuse: Konrad Zuse was born on June 22, 1910 in Berlin, Germany. There he attended the Berlin Institute of Technology, graduating in 1935. After he worked for the Ford Motor Company, but then switched to working on aircrafts in Berlin. In his spare time he would work on a machine that he dreamed would do his boring calculations for him. He called this device the Z1, but was never actually finished due to the off mechanics of the machine. In 1939 he was drafted into the military, where he was able to get the resources he needed to work on his new machine, the Z2. In 1941 he was able to start his own company that would manufacture these machines. Overtime Zuse created the Z3, an electromechanical computer that was the first of its kind. During the war, Zuse’s company and his Z1, Z2, and Z3 models were destroyed by an Allied air raid. Luckily, his new Z4 model, currently being built, was sent to a safe location before the air raid. When the Z4 was completed, Eduard Stiefel ordered a Z4 model for the Swiss Federal Institute of Technology, which turned out very useful and reliable. Konrad Zuse died at the age of eighty five on December 18th, 1995.

Alan Turing: Sometimes refered to as the "father of computing", he had a major influence on the evolution of computers.

Alan Turing: Alan Turing was born in London, England, to Julius and Sara Turing. After graduating from high school, Turing became an Undergraduate at King's College, in Cambridge. He graduated as a math major, and was deemed a fellow for his work on central limit theorem. One of his largest work was his paper, "On Computable Numbers, with an Application to the Entscheidungsproblem." (The Entscheidungsproblem was an invention by Kurt Godel.) In 1938, Turing began working for the British Government as a cryptographer. After World War II, he became focused on designing ACE (Automatic Computing Engine). At the same time as this, he presented the first design of a, "stored-program computer." Later in life, he was subjected to chemical castration for being homosexual, and eventually died from cyanide poisoning.

Difference Engine: []

Difference Engine: In 1930, Vannevar Bush built a difference engine that was partially electronic. His difference engine was able to solve differential equations. The initial difference engines were often used to approximate logorithmic and trigonometric functions through the use of an approximated Taylor or MacLaurin Series. The machine use varying columns to work to a solution.
