Overview
David Bradley was born in 1949, earned his bachelor's degree in electrical engineering from the University of Dayton, and his master's and PhD from Purdue University. In 1980, he was one of the twelve engineers who built the original IBM Personal Computer, the machine that made "PC" a household word, and he was responsible for writing the ROM BIOS, the code that runs when a computer first turns on. While building it, he added a way for the engineers to restart the machine without powering it down and waiting: hold Control and Alt and press Delete. He chose those three keys because they were so far apart on the keyboard that no one could hit them by accident. The shortcut was meant for programmers, but it stayed in the finished product and became one of computing's best-known commands. At the PC's twentieth anniversary in 2001, Bradley joked, "I may have invented it, but I think Bill made it famous," a reference to Bill Gates and Windows. He retired from IBM in 2004 and later taught engineering at Florida Atlantic University and North Carolina State University.
Why He Matters
David Bradley built the tool that every IT support specialist has used more times than they could count. Ctrl+Alt+Delete is where troubleshooting begins on a frozen Windows computer, and it exists because an engineer solved a small, practical problem for himself and his colleagues. His story captures something true about the field: the most useful ideas in technology are often not grand inventions but simple fixes that make the daily work of using a computer a little less painful. For young people, he reminds them that the people who keep technology working are as important as the people who dream it up.
