Two men, Herman Hollerith and James Powers, developed a new punched-card system that could automatically read information on cards without human (Dolotta, 1985). ... It was slow, requiring 3 to 5 seconds for a multiplication, but it was fully automatic and could complete long computations without human intervention. ... This machine became known as ENIAC, for Electrical Numerical Integrator And Calculator (Chposky, 1988). It could multiply two numbers at the rate of 300 products per second, by finding the value of each product from a multiplication table stored in its memory. ... In 1945 he un...

Another early calculator, later called Napier's Bones, made its debut in the early 1600's. This device, invented by Charles Napier, consisted of a series of rods that could be used to perform multiplication. ... It was not until 1820 that a mechanical calculator, developed by Charles Xavier Thomas, was introduced that could perform all four basic arithmetic operations. While Thomas was busy creating the desktop calculator, Charles Babbage (a mathematics professor in Cambridge, England), began to design a more complex machine. ... This monster of a machine was known as the Electri...
