Íàçâàíèå: The First Electronic Computer: The Atanasoff StoryÀâòîðû: Burks A.R., Burks A.W. Àííîòàöèÿ: I read the Alice Burks book "Who Invented the Computer?" before I read this one, and I'm surprised to find this one even worse. It appears to have been written by a god and goddess who know what is in the hearts of men, especially John Mauchly and Pres Eckert. I think the first page should have started with their philosophy of John and Pres's characters expressed on p.181, "they were greedy, for fame and fortune, and did not want to acknowledge any prior invention." This is the premise under which they operate so of course they interpret everything as a proof of this premise. I knew Arthur Burk as a nice, mild-mannered man in the style of the Mr. Milquetoast depicted in the New Yorker cartoon. Apparently, he married a woman with magical powers who turned him into this vicious all-knowing author. I wonder if he would have been as self-righteous if he had been included on the ENIAC patent. He would probably have been able to stifle his virtue and never even dream of beating the drums for Atanasoff. They even include testimony of Mrs. Atanasoff that makes her sound as gracious as a pig at a trough. Of course, she knew Mauchly was staying with them. Her husband had told him that they had plenty of room and he was welcome.
