The Man Who Invented the Computer: The Biography of John Atanasoff, Digital Pioneer by Jane Smiley

3.0

So far (p. 28) Smiley has asserted a couple of head-scratchers: "The measurement required by an analog calculator would be replaced by counting. Since this is similar to the way a child counts on his fingers, this came to be known as digital calculation."

This is more the early cross-pollination that led to computers rather than the biography of a single man; the title is misleading but the book is interesting so that's okay.
