Dr. Mark Dean
(b. 1957)

A lot of kids growing up today aren't told that you can be whatever you want to be. There may be obstacles, but there are no limits.
—Mark Dean

When you think PC (personal computer), Mark Dean does not readily come to mind. Mark who?, you may ask.

Dr. Mark Dean is an engineer who has played a leading role in the development of the personal computer—which has spearheaded the technological revolution in education, industry and every facet of modern life.

As a member of an IBM research team to develop a more effective desktop computer, which ultimately became known as the IBM PC, Dr. Dean and his colleague Dennis Moeller created the interior architecture allowing the computer to share information with peripheral devices such as disk drives, printers and scanners.

Although this development helped place the power of the personal computer at the disposal of every business and home, Dr. Dean did not rest on his laurels. Instead, he moved on to develop the PC AT (Advanced Technology) which defined the industry standard architecture for most personal computers used today. Dr. Dean is also responsible for leading the team that developed the first 1-gigahertz microprocessor chip at his Austin Research Lab.

Dr. Dean holds 3 of the original 9 patents on which the PC is based, and has a total of more than 30 patents pending.

In 1995 he was named an IBM Fellow, becoming the first African-American to achieve this honor, which is held by only 50 employees of the current workforce of 200,000.

In 1997 Dr. Dean, along with his co-inventor Dennis Moeller, was inducted into the National Inventors Hall of Fame, where he joined two other eminent black members, George Washington Carver and Dr. Percy Julian.

During his 20-year career, he has held a number of engineering positions in the field of computer system hardware architecture and design. Dr. Dean is currently Vice President of Systems in IBM Research, responsible for developing next-generation hardware and systems technologies: systems covering pervasive to supercomputing environments.
