Today CNN posted a Timeline for Computing Power. Being a librarian and a blogger on information issues, I collect timelines related to all aspects of information history. Last week I attended a meeting where someone said that the Internet will double every 11 months. What have we wrought with these computers?

But I do have a few quibbles with the timeline. It dates the history of computing to only 1946. In fact, the first use of the word “computer” dates to the 1640’s and referred to a human being who performed calculations. These human generated calculations would be compiled in to navigation tables or interest rate tables.
How Did They Overlook Charles Babbage?
My big beef is with the omission of Charles Babbage who developed the Difference Engine in 1822. It was capable of computing several sets of numbers and producing a hard copy of the results. In 1837 Babbage proposed an Analytical Engine, a hand cranked, mechanical digital computer which anticipated virtually every aspect of present day computers. It was almost 100 years until another all purpose computer was conceived. According to James Gleik’s book, The Information, Babbage was inspired by the Jaquard fabric loom,invented in 1804 and which used punched cards to design the fabric patterns.
