I highly recommend "Go To" by Steve Lohr [1]. The book follows a chronological path from the pre-Hopper/Turing era through Apache and the early open source movement. We learn history of the following languages: FORTRAN, COBAL, Unix, C, BASIC, Visual Basic, Algol, Pascal, C++. Also covered are the founding stories of IBM, Microsoft and Macintosh and their "business" practices.
