Study Notes
Early Counting Tools
- Humans have used various tools for counting for centuries
- Sticks, fingers, stones, beads, pebbles, leaves, chicken bones, seeds, shells, and rope were all used
Key Individuals and Inventions
- Gottfried Wilhelm Leibniz (1646-1716) developed the Step Reckoner, a mechanical calculator that could perform basic mathematical operations
- Charles Babbage (1792-1871) is considered the Father of the Computer and designed the Difference Engine and Analytical Engine, precursors to modern computers
- Lady Augusta Ada Byron, known as the first computer programmer, collaborated with Babbage
- John Napier (1550-1670) invented Napier's Bones, made of ivory, for multiplication and long division, also capable of calculating square roots
- William Oughtred created the Slide Rule in 1620, which facilitated faster calculations
- Blaise Pascal invented the Pascaline in 1642 to assist with tax computations
- Joseph Marie Jacquard (1752-1832) created a loom that used punch cards to store data
- Herman Hollerith (1860-1929) developed a card reader to count census data, using it to win a government contract for the 1890 census
- Thomas Edison invented the light bulb amongst other devices influential to computing
- John Ambrose Fleming created vacuum tubes essential for early computers
- Lee DeForest improved on these designs with the Audion tube
First-Generation Computers
- Kelvin’s Tide Predictor was developed by William Thomson in 1876 to predict tides at specific times
- Differential Analyzer was created by Vannevar Bush at MIT in 1930; it combined mechanical and electronic components and used vacuum tubes for storage
- MARK I was built in 1943
- IBM 701 (1952) was also known as the "defense calculator" and was built in separate units for easier shipping and installation; it was the first computer to use magnetic plastic tape for storage
- IBM 650 (1953) was a smaller, more affordable computer designed for a wider range of customers; it could read and write from magnetic tape and punched cards
