Mark Edward Dean [2] (born March 2, 1957) [1] is an American inventor and computer engineer. He developed the ISA bus with his partner Dennis Moeller, and he led a design team for making a one-gigahertz computer processor chip. [3] He holds three of nine PC patents for being the co-creator of the IBM personal computer released in 1981. [4] In 1995, Dean was named the first ever African-American IBM Fellow. [5]
Dean was elected as a member into the National Academy of Engineering in 2001.
In 2000, Mark discussed a hand held device that would be able to display media content, like a digital newspaper. [6] [7] In August 2011, Dean stated that he uses a tablet computer instead of a PC in his blog. [8] [9]
Dean was born in Jefferson City, Tennessee. Dean displayed an affinity for technology and invention at a young age. [10] His father, James, worked bob[ clarification needed ] electrical equipment for turbines and spillways. Dean's father would often bring him on work trips, introducing him to engineering. [11] When Dean was young, he and his father constructed a tractor from scratch. [12] In middle school, Dean had made up his mind on becoming a computer engineer. [11] He attended Jefferson City High School in Tennessee, where he excelled in both academics and athletics. [10] [13] While in high school during the 1970s, Dean built his own personal computer. [6]
Dean is the first African-American to become an IBM Fellow, [14] which is the highest level of technical excellence at the company. In 1997, he was inducted into the National Inventors Hall of Fame. [13] [15] He was elected to the National Academy of Engineering in 2001. [16] In 1997, Dean was awarded the Black Engineer of the Year Presidents Award. [17] From August 2018 to July 2019, Dean was the interim dean of the UT's Tickle College of Engineering. [18] [19]
As of April 26, 2019, April 25 is officially Mark Dean Day in Knox County, Tennessee. [20]
Dean graduated with a bachelors in electrical engineering during 1979. [21] Soon after, he got a job at IBM as an engineer. [6] [21] His first task at the company was to create a word processor adapter for IBM's Datamaster terminal. [6] 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. [6] In the same year, Dean earned his master's degree in electrical engineering. [21] In 1999, Dean and his team developed a gigahertz microchip, the first in the world.
Dean was the President overseeing the company's Almaden Research Center in San Jose, California. [16] At one point, Dean was CTO for IBM Middle East and Africa. [22] He retired from the company in 2013 and became a professor at University of Tennessee. [21] Mark Dean is the John Fisher Distinguished Professor in the Department of Electrical Engineering and Computer Science at the University of Tennessee. [21] [23]
Dean now holds more than 20 patents, [17] [24] and his work led to development of the color PC monitor. [25]
