history of technology


charles babbage


In 1837, Charles Babbage proposed the first general mechanical computer, the Analytical Engine. The Analytical Engine contained an Arithmetic Logic Unit (ALU), basic flow control, and integrated memory and is the first general-purpose computer concept. Unfortunately, because of funding issues, this computer was also never built while Charles Babbage was alive.

like father like son


In 1910, Henry Babbage, Charles Babbage's youngest son, was able to complete a portion of this machine and was able to perform basic calculations.

First concepts of what we consider a modern computer


The Turing machine was first proposed by Alan Turing in 1936 and became the foundation for theories about computing and computers. The machine was a device that printed symbols on paper tape in a manner that emulated a person following a series of logical instructions. Without these fundamentals, we wouldn't have the computers we use today.

First programmable computer


The Z1 was created by German Konrad Zuse in his parents' living room between 1936 and 1938. It is considered to be the first electro-mechanical binary programmable computer, and the first really functional modern computer.

First commercial computer


In 1942, Konrad Zuse begin working on the Z4 that later became the first commercial computer. The computer was sold to Eduard Stiefel, a mathematician of the Swiss Federal Institute of Technology Zurich on July 12, 1950.

The first electric programmable computer


The Colossus was the first electric programmable computer, developed by Tommy Flowers, and first demonstrated in December 1943. The Colossus was created to help the British code breakers read encrypted German messages.

The first digital computer


Short for Atanasoff-Berry Computer, the ABC began development by Professor John Vincent Atanasoff and graduate student Cliff Berry in 1937. Its development continued until 1942 at the Iowa State College (now Iowa State University).

The first stored program computer


The early British computer known as the EDSAC is considered to be the first stored program electronic computer. The computer performed its first calculation on May 6, 1949 and was the computer that ran the first graphical computer game, nicknamed "Baby".

The first computer company


The first computer company was the Electronic Controls Company and was founded in 1950 by J. Presper Eckert and John Mauchly, the same individuals who helped create the ENIAC computer. The company was later renamed to EMCC or Eckert-Mauchly Computer Corporation and released a series of mainframe computers under the UNIVAC name.

First stored program computer


First delivered to the United States government in 1951, the UNIVAC 1101 or ERA 1101 is considered to be the first computer that was capable of storing and running a program from memory.

IBM's first computer


On April 7, 1953 IBM publicly introduced the 701; its first commercial scientific computer.

The first computer with RAM


MIT introduces the Whirlwind machine on March 8, 1955, a revolutionary computer that was the first digital computer with magnetic core RAM and real-time graphics.
