Mark E. Dean
(born March 2, 1957) is an inventor and a computer scientist. He holds three of the nine original IBM patents upon which the IBM PC personal computers were based. He led the team that developed the ISA bus, and he led the design team responsible for creating the first one-gigahertz computer processor chip.
Born in Jefferson City, Tennessee, Dean holds a bachelor’s degree in electrical engineering from the University of Tennessee, a master’s degree in electrical engineering from Florida Atlantic University and a Ph.D. in electrical engineering from Stanford University.
Dean is the first African-American to become an IBM Fellow which is the highest level of technical excellence at the company. In 1997, he was inducted into the National Inventors Hall of Fame. Currently, he is an IBM Vice President overseeing the company’s Almaden Research Center in San Jose, California.
Dean now holds more than 20 patents.
Dean led a team that developed the interior architecture (ISA systems bus) that enables multiple devices, such as modems and printers, to be connected to personal computers.
Dean made history again by leading the design team responsible for creating the first 1-gigahertz RISC processor chip, another significant step in making computers faster and smaller.
As a child, Mark Dean excelled in math. In elementary school, he took advanced level math courses and, in high school, Dean even built his own computer, radio, and amplifier. Dean continued his interests and went on to obtain a bachelor’s degree in electrical engineering from the University of Tennessee, a masters degree in electrical engineering from Florida Atlantic University and a Ph.D. in electrical engineering from Stanford. He is one of the most prominent black inventors in the field of computers.
Dr. Mark Dean started working at IBM in 1980 and was instrumental in the invention of the Personal Computer (PC). He holds three of IBM’s original nine PC patents and currently holds more than 20 total patents. The famous African-American inventor never thought the work he was doing would end up being so useful to the world, but he has helped IBM make instrumental changes in areas ranging from the research and application of systems technology circuits to operating environments. One of his most recent computer inventions occurred while leading the team that produced the 1-Gigahertz chip, which contains one million transistors and has nearly limitless potential.
