In the spring of 1981, David Bradley was part of a select team working from a nondescript office building in Boca Raton, Fla. His task: to help build IBM’s new personal computer. Because Apple and RadioShack were already selling small stand-alone computers, the project (code name: Acorn) was a rush job. Instead of the typical three- to five-year turnaround, Acorn had to be completed in a single year.
So Bradley created a keyboard shortcut that triggered a system reset without the memory tests. He never dreamed that the simple fix would make him a programming hero, someone who’d someday be hounded to autograph keyboards at conferences. And he didn’t foresee the command becoming such an integral part of the user experience.
Bradley joined IBM as a programmer in 1975. By 1978, he was working on the Datamaster, the company’s early, flawed attempt at a PC. It was an exciting time—computers were starting to become more accessible, and Bradley had a chance to help popularize them.
And yet, few of these consumers were aware of Bradley’s shortcut quietly lingering in their machines. It wasn’t until the early 1990s, when Microsoft’s Windows took off, that the shortcut came to prominence. As PCs all over the country crashed and the infamous “blue screen of death” plagued Windows users, a quick fix spread from friend to friend: ctrl+alt+del. Suddenly, Bradley’s little code was a big deal. Journalists hailed “the three-finger salute” as a saving grace for PC owners—a population that kept growing.
In 2001, hundreds of people packed into the San Jose Tech Museum of Innovation to commemorate the 20th anniversary of the IBM PC. In two decades, the company had moved more than 500 million PCs worldwide. After dinner, industry luminaries, including Microsoft chairman Bill Gates, sat down for a panel discussion. But the first question didn’t go to Gates; it went to David Bradley. The programmer, who has always been surprised by how popular those five minutes spent creating ctrl+alt+del made him, was quick to deflect the glory.
“I have to share the credit,” Bradley joked. “I may have invented it, but I think Bill made it famous.”
