Bradley is the man who gave the world "control-alt-delete." "It was not a memorable event," said Bradley, a longtime IBM employee, speaking of that day in 1980 or '81 when he discovered control-alt-delete. "It wasn't intended as something we were going to tell the customers about," he says. "Then it turned out that this reset was a problem-solver for people who were writing the programs and writing the instruction manuals." Thank this guy for ‘control-alt-delete’
