Bachelor of Science, Electrical Engineering
The next time your computer freezes, you can thank a Flyer when you’re quickly able to unlock it. Best known for inventing the three-key sequence known as “Control-Alt-Delete,” David Bradley holds 10 patents related to computer design and was one of the original 12 engineers who began work on the IBM personal computer in 1980.
He was responsible for the Basic Input/Output System, known as “BIOS,” writing the code that controlled the display, keyboard, diskette drive, printer and other system hardware devices. Because two of his patents were critical to IBM’s success, he was honored with IBM’s Corporate Patent Portfolio Award. He also wrote a technical manual for the PC and founded a PC architecture group to assist in establishing consistency across IBM products.
After earning a bachelor’s in electrical engineering from UD, Bradley earned a doctorate in electrical engineering from Purdue University. With a busy schedule, keyboard shortcuts are still his favorite time-saver.
“I started using PCs when everything was entered on the command line; no drag/drop/click. So, the shortcuts I’ve learned through the years, like Control-C to copy, or Control-V to paste, make a difference. I hate moving my hand to the mouse to do those things,” he said, noting that he’s not immune to a computer’s time vacuum, either.
“My favorite time wasters are probably just like everybody else. Reading blogs by people I don't know about things I really don't care about, just because they are interesting, reading things discovered while looking something else up,” he said. “One not like everybody else — I love taking a PC apart to make it run faster or better.”
On top of a 30-year career at IBM, Bradley has been an adjunct professor at Florida Atlantic University and North Carolina State University.
