David J. Bradley
Man behind "Control-Alt-Delete" (a.k.a. three-finger salute)


Bradley is most famous for inventing the "Control-Alt-Delete" (a.k.a. three-finger salute) key combination that was used to reboot the computer.Bradley received a doctorate in electrical engineering from Purdue University in 1975. He was one of the original 12 engineers assigned to IBM’s PC project in Boca Raton, Fla., in 1980. Bradley also invented the CTRL-ALT-DELETE
sequence as a command in the BIOS. (CTRL-ALT-DELETE was originally used to reboot a computer and now calls up the Task Manager in Windows.) Bradley inserted the CTRL-ALT-DELETE sequence as a hidden command to let programmers reset their machines at the end of an unsuccessful programming routine. Word leaked out, and the public popularized the shortcut.
The original idea was simply to reset early PCs without turning them off. Microsoft adopted control-alt-delete to help ensure people powered down correctly, then to handle "administrative functions" such as the vital "end task" feature for computer software that crashes or otherwise gets stuck.

Bradley chose the control and alt keys because he needed two shift keys to make the operation work, and he chose the delete key because it was on the opposite side of the keyboard. He didn't want people to hit control-alt-delete by accident.

At the 20th anniversary celebration of the release of IBM’s first desktop computer, Bradley minimized his creation of the famous command. “I didn’t realize I was creating a cultural icon when I invented it,” Bradley stated. “I invented it, but Bill [Gates] made it famous.”
