At Illinois, Ellis continued to work on computer systems, in particular the hardware, software, and applications of ILLIAC IV supercomputer. At Beloit, he helped set up the school’s first computer laboratory, a place where he spent many hours developing his interest in computers. Using what he had learned from the manuals, Ellis showed the company’s employees how to reuse old punch cards.Įllis attended Beloit College in Wisconsin, where he received a bachelor’s degree in mathematics and physics. One day, an important project had to be run, but there were no more punch cards (which were the only means of input at the time). During his free time, Ellis read the computer’s manuals and became a self-taught expert. He landed a job as a night watchman at a local insurance company that had recently purchased an expensive computer.
