Mark Dean (computer scientist)
Mark E. Dean (born March 2, 1957)[1] was an American inventor and computer engineer. He developed the ISA bus, and he led a design team for making a one-gigahertz computer processor chip.[2] He holds three of nine PC patents for being the co-creator of the IBM personal computer released in 1981.[3] In 1995, Dean was named the first ever African-American IBM Fellow.[4]

Dean was elected as a member into the National Academy of Engineering in 2001 for innovative and pioneering contributions to personal computer development.
In 2000, Mark discussed a hand held device that would be able to display media content, like a digital newspaper.[5][6] In August 2011, Dean stated that he uses a tablet computer instead of a PC in his blog.[7][8]
Early life edit
Dean was born in Jefferson City, Tennessee. Dean displayed an affinity for technology and invention at a young age.[9] His father, James, worked with electrical equipment for turbines and spillways. James would often bring Mark with him on work trips, introducing him to engineering.[10] When Mark was young, he and his dad constructed a tractor from scratch.[11] In middle school, Mark had made up his mind on becoming a computer engineer.[10] Dean attended Jefferson City High School in Tennessee, where he excelled in both academics and athletics.[9][12] While in high school, during the 1970s, Mark built his own personal computer.[5]
Recognition edit
Dean is the first[13] 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.[12][14] He was elected to the National Academy of Engineering in 2001.[15] In 1997, Dean was awarded the Black Engineer of the Year Presidents Award.[16] From August 2018 to July 2019, Dean was the interim dean of the UT's Tickle College of Engineering.[17][18]
As of April 26, 2019, April 25 is now officially Mark Dean Day in Knox County, Tennessee.[19]
Career edit
Mark graduated with a bachelor's degree in electrical engineering during 1979.[20] Soon after, Mark got a job at IBM as an engineer.[5][20] His first task at the company was to create a word processor adapter for IBM's Datamaster terminal.[5] During this time, he also created the ISA bus that allowed additional components to be connected to a PC. His work got him promoted in 1982 to chief engineer of PC design, where he worked with a team to develop the IBM PC.[5] In the same year, Mark earned his master's degree in electrical engineering.[20] 17 years later, in 1999, Dean and his team developed a gigahertz microchip, the first in the world.
Dean was an IBM Vice President overseeing the company's Almaden Research Center in San Jose, California.[15] At one point, Mark was CTO for IBM Middle East and Africa.[21] He retired from the company in 2013 and became a professor at University of Tennessee.[20] Mark Dean is the John Fisher Distinguished Professor in the Department of Electrical Engineering and Computer Science at the University of Tennessee.[20][22]
Dean now holds more than 20 patents,[16][23] and his work led to development of the color PC monitor.[24]
