Chapter 3 tells the story of the visionaries that first imagined the computer. In the 19th century, Charles Babbage invented a mechanical computer but failed in his attempts to build it. He and Ada Lovelace wrote a series of programs for the proposed machine. These programs were the first transcriptions of algorithms into sequences of machine executable instructions. After Babbage’s failure, the idea of building a real computer was abandoned for fifty years. As a young PhD student, Alan Turing forever defined the relationship between algorithms and computers. According to his definition, a computer is a machine that performs algorithms. He devised a theoretical computer that allowed him to investigate the limits of computation. This, before a single computer was ever built. Turing went on to work as a cryptographer during World War II. Turing outlined the future of computing but tragically died at the age of 41.
