Mark E. Dean (born March 2, 1957) is a Black American inventor and computer engineer. He was part of the team that developed the ISA bus, and he led a design team for making a one-gigahertz computer processor chip.[1] He holds three of nine PC patents for being the co-creator of the IBM personal computer released in 1981.[2] In August 2011, writing in his blog, Dean stated that he now uses a tablet computer instead of a PC.[3][4]

Early life[edit]

Mark E. Dean was born in Jefferson City, Tennessee. Dean displayed an affinity for technology and invention at a young age.[5] When Mark was young, he and his dad constructed a tractor from scratch.[6]


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.[7]


Dean is the first[8] 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.[7][9]


Currently, he is the interim dean of the Tickle College of Engineering [10] and is the John Fisher Distinguished Professor in the Department of Electrical Engineering and Computer Science at the University of Tennessee.[11] He was previously CTO for IBM Middle East and Africa[12] and was an IBM Vice President overseeing the company's Almaden Research Center in San Jose, California prior to that.[13] Dean now holds more than 20 patents.[14][15] Dean was part of the team that developed the interior architecture (ISA systems bus) that enables multiple devices, such as modems and printers, to be connected to personal computers.
