Two lesser known books that I enjoyed: 1) "Colossus: The secrets of Bletchley Park's code-breaking computers", and 2) "The Dream Machine: J.C.R. Licklider and the Revolution That Made Computing Personal".

One thing I learned from the "Colossus" book was the contribution of British engineers to early computers (Tommy Flowers in particular). They didn't get the credit they deserved because their work was kept secret for so long.
