Study Notes
Early Computing
- The history of computers dates back over 200 years, with early designs originating in the 19th century.
- Mathematicians and entrepreneurs envisioned and created mechanical calculating machines to solve complex numerical problems.
- Charles Babbage, an English mathematician, conceived of a steam-driven calculating machine called the "Difference Engine" in 1821, but it was not successful due to technological limitations.
- Ada Lovelace, an English mathematician and daughter of Lord Byron, wrote the first computer program in 1848 while translating a paper on Babbage's Analytical Engine.
- Lovelace's annotations on the translation included a detailed algorithm for calculating Bernoulli numbers, solidifying her place as the world's first computer programmer.
- The Swedish inventor Per Georg Scheutz and his son Edvard designed the first printing calculator in 1853, which could calculate tabular differences and print the results.
- Herman Hollerith developed a punch-card system in 1890 to process the 1890 US Census, saving the government years of calculations and millions of dollars.
- Hollerith founded a company that eventually evolved into IBM.
