Hackers by Steven Levy is an incredible story of the industry’s early years (60-80’s) and the characters that were in it for the “love of the game” vs what is more common now (“status and money”). A lot of heroes like woz, but who are less well known in this day and age (Gosper and Greenblatt!). If you are familiar with and a fan of Dealers of Lightning or Dream Machine, check out Hackers! (this is not a paid endorsement).
