The First Computer Bug

American engineers have been calling small flaws in machines “bugs” for over a century. Thomas Edison talked about bugs in electrical circuits in the 1870s. When the first computers were built during the early 1940s, people working on them found bugs in both the hardware of the machines and in…

John Von Neumann

Von Neumann’s interest in computers differed from that of his peers by his quickly perceiving the application of computers to applied mathematics for specific problems, rather than their mere application to the development of tables. During the war, von Neumann’s expertise in hydrodynamics, ballistics, meteorology, game theory, and statistics, was…

Harvard Mark II

Howard Aiken and Grace Hopper designed the MARK series of computers at Harvard University. The MARK series began with the Mark I in 1944. Imagine a giant roomful of noisy, clicking metal parts, 55 feet long and 8 feet high. The 5-ton device contained almost 760,000 separate pieces. It was…
