Writing texts in the early 1980's to fulfill the critical need in this burgeoning field, authors of computer science texts generally not mathematics or computer science historians relied upon readily available historical sources that do not stand up to critical analysis. These sources include Charles Babbage's memoirs [2], W. W. R. Ball's biased celebration of Cambridge University mathematics [3], and E. T. Bell's concise and colorful tributes to various mathematicians [6]. But these tributes and memoirs, cited in virtually every historical article, are no substitute for critical analysis of historical events.
