Electronics Era 1900-1964

1.    In 1926, Dr. Julius Edgar Lilienfield from New York filed for a patent on a transistor.

2.    Konrad Zuse, a German engineer, completes the 1^st general purpose programmable calculator in 1941.

3.    Colossus, a British computer used for code-breaking, is operational by the end of 1943.

4.    ENIAC (Electronic Numerical Integrator Analyzor and Computer) is developed by Ballistics Research Lab in Maryland and built by the University of Pennsylvania and completed in 1945.

5.    The transistor is developed by Bell Telephone Laboratories in 1947.

6.    UNIVAC (Universal Automatic Computer) is developed in 1951 and can store 12,000 digits in random access mercury-delay lines.

7.    EDVAC (Electronic Discrete Variable Computer) is completed for the Ordinance Department in 1952.

8.    Texas Instruments and Fairchild Semiconductor both announce the integrated circuit in 1959.

9.    The IBM 360 is introduced in April of 1964 and quickly becomes the standard institutional mainframe computer. By the mid-80s the 360 and its descendents have generated more than $100 billion in revenue for IBM.
