Biography

Early life

Carmack, son of local television news reporter Stan Carmack, grew up in the Kansas City Metropolitan Area where he became interested in computers at an early age. He attended Shawnee Mission East High School in Prairie Village, Kansas and Raytown South High School in nearby Raytown, Missouri.

As reported in David Kushner's Masters of Doom, when Carmack was 14, he broke into a school to help a group of kids steal Apple II computers. To gain entry to the building, Carmack concocted a sticky substance of thermite mixed with Vaseline that melted through the windows. However, an overweight accomplice struggled to get through the hole, and opened the window, setting off a silent alarm and alerting police. John was arrested, and sent for psychiatric evaluation (the report mentions 'no empathy for other human beings' and describes Carmack as 'a brain on legs'). Carmack was then sentenced to a year in a juvenile home.
