Enigma Machine Invented
An Enigma machine is of family of related electro-mechanical rotor machines used for encryption and decryption of secret messages. The first Enigma was invented by German engineer Arthur Scherbius at the end of
World War I.This machine was used by the germans with great success in world war II -
The first differencial analyzer
The differential analyser was a mechanical analog computer designed to solve differential equations by integration, using wheel-and-disc mechanisms to perform the integration. It was one of the first advanced computing devices to be used operationally. Using a set of gears and shafts, much like Babbage, the machine can handle simple calculus problems, but accuracy is a problem. -

Konrad Zuse was a German engineer and computer pioneer. His greatest achievement was the world's first functional program-controlled Turing-complete computer, the Z3, in 1941 (the program was stored on a punched tape). -
The Havard Mark I is introduced
The automatic sequence-controlled calculator called Mark I by Harvard University was the first large-scale automatic digital computer in the United States. Some consider it the first universal calculator. Use a paper tape to store the instructions -
First stored-program computer
Teams around the world work on a "stored program" machine. The first, nicknamed "Baby", is a prototype of a much larger machine under construction in Britain and is shown in June 1948. The Manchester Small-Scale Experimental Machine (SSEM), nicknamed Baby, was the world's first stored-program computer. It was built at the Victoria University of Manchester by Frederic C. Williams, Tom Kilburn and Geoff Tootill, and ran its first program on 21 June 1948. -

Books & Documents Appear in the Internet
Project Gutenberg tried to create and store books and documents in the public domain available electronically, for free, in various eBook and electronic formats.
Michael Hart gained access to a large block of computing time and envisigaed that the future of computers wasn’t in computing itself, but in the storage, retrieval and searching of information -
Texas Instruments introduces the first "pocket calculator
It weighs 2.5 pounds, just a bit more than a bag of sugar!! Big pockets then? It was called the TI-58. -
