Study Notes
Early Mechanical Calculators
- Blaise Pascal invented the Pascaline between 1642 and 1644, enabling addition and subtraction.
- Gottfried Wilhelm von Leibniz designed the Step Reckoner in 1673, advancing Pascal's work by incorporating multiplication through repeated addition and advocating for the binary system.
Innovations in Automation
- Joseph Marie Jacquard introduced a loom in 1801 that used punched wooden cards, a precursor to modern punch card systems utilized in early computers.
Commercially Successful Calculators
- Thomas de Colmar patented the Arithometer in 1820, marking the first successful commercial mechanical calculator capable of performing all four basic arithmetic operations. Production spanned from 1851 to 1915.
The Birth of Modern Computing
- Charles Babbage created the Differential Engine in 1822, designed to tabulate polynomial functions using a decimal system powered by a manual crank.
- In 1837, Babbage proposed the Analytical Engine, which is considered the first mechanical general-purpose computer, earning him recognition as the father of modern computers.
Pioneer in Computer Programming
- Augusta Ada King, Countess of Lovelace, collaborated with Babbage between 1842 and 1844, identifying the Analytical Engine's extensive applications beyond mere calculations. She published the first algorithm intended for implementation by a machine, earning her the title of the first computer programmer.
Advancements in Data Processing
- Herman Hollerith invented the punched card tabulating machine in 1884, leading to the emergence of semi-automatic data processing systems and dominating the industry for nearly a century.
