ENIAC – The First Computer Introduced Into Public

ENIAC – The First Computer Introduced Into Public

Harald Sack
On February 13, 1946, J. Presper Eckert and John Mauchly introduced Electronic Numerical Integrator and Computer, or ENIAC, the first general purpose, electronic computer. ENIAC was a giant step forward in computing technology. “Where a calculator like the ENIAC today is equipped with 18,000 vacuum tubes and weighs 30 tons, computers in the future may have only 1,000 vacuum tubes and perhaps weigh only 1½ tons.” – Andrew Hamilton, “Brains that Click”,…

Intel 4004 – The World’s First Microprocessor

Intel 4004 – The World’s First Microprocessor

Harald Sack
On November 15, 1971, Intel presented the Intel 4004 microprocessor, the world’s very first commercially available 4-bit central processing unit (CPU). It was the first complete CPU on one chip. By the time, this revolutionary microprocessor, the size of a little fingernail, delivered the same computing power as the first electronic computer built in 1946, which filled an entire room. Subsequently, the successors to the 4004 should drive the digital revolution. A New…

Tom Kilburn and the First Stored-Program Computer

Harald Sack
On August 11, 1921, English engineer Tom Kilburn was born. Kilburn became known for having written the computer program used to test the first stored-program computer, the Small-Scale Experimental Machine, SSEM, also known as “The Baby” in 1948. “… the most exciting time was June 1948 when the first machine worked. Without question. Nothing could ever compare with that.” Tom Kilburn, Autumn 1992 Tom Kilburn was born in Dewsbury, Yorkshire, England and…

The Antikythera Mechanism – an Ancient Analog Computer

Tabea Tietz
On May 17, 1902, Greek archaeologist Valerios Stais discovers the Antikythera mechanism, an ancient mechanical analog computer, designed to predict astronomical positions and eclipses. The Discovery of the Antikythera Mechanism The famous mechanism was discovered in a shipwreck near the Greekisland of Antikythera. In October 1900, a group of sponge divers discovered the wreck and retrieved a great number of artifacts dating back to the end of the second century BC, which…

Howard Aiken and the Harvard Mark I Computer

Tabea Tietz
On March 9, 1900, computer pioneer Howard Hathaway Aiken was born. He was the original conceptual designer behind IBM’s Harvard Mark I computer, forerunner of the modern electronic digital computer. “The desire to economize time and mental effort in arithmetical computations, and to eliminate human liability to error is probably as old as the science of arithmetic itself.” — Howard Aiken, in Proposed Automatic Calculating Machine (1937) Early Years Howard Aiken’s parents…

Konrad Zuse – The German Inventor of the Computer

Tabea Tietz
On December 18, 1995, German engineer and computer pioneer Konrad Zuse passed away. He is renowned to have constructed the very first functional program-controlled Turing-complete computer,which was freely programmable and provided binary floating point arithmetics: the Z3, which became operational in May 1941. “The belief in a certain idea gives to the researcher the support for his work. Without this belief he would be lost in a sea of doubts and insufficiently…

George Boole – The Founder of Modern Logics

Harald Sack
On December 8, 1864, British mathematician and logician George Boole passed away. He is best known as the inventor of the prototype of what is now called Boolean logic, which became the basis of the modern digital computer. Thus, Boole also is regarded as one of the founders of the field of computer science. “It appeared to me that, although Logic might be viewed with reference to the idea of quantity, it…
