The story of one of the original "killer apps" begins in Ann Arbor, Michigan (USA) with a college professor named Glenn Knoll. Glenn was a photo enthusiast who maintained a darkroom in the family basement. He was also a technology aficionado intrigued by the emergence of the personal computer. His two sons, Thomas and John, inherited their father's inquisitive nature. And the vision for future greatness began with their exposure to Glenn's basement darkroom and with the Apple II Plus that he brought home for research projects.
"Photography was a hobby of mine in high school," explained Thomas in an interview for the Michigan Engineer. "In dad's darkroom, I learned how to make black-and-white and color prints, how to balance color and contrast."
While Thomas learned about image manipulation in the basement darkroom, John was attracted to the odd-shaped box known as a personal computer that his dad had brought home. "The first real computer I ever actually sat down and used was in 1978. I was a 16-year-old high school student when my dad got an Apple II Plus with 64k of RAM," John recalls during an interview for his AppleMasters biography.
