Mark Dean

Life story


Young Genius


Mark Dean invented the colour PC monitor, at a time when there were problems with displaying the contents of the computer in the best way possible. The colour monitor was important because it helped people using it to look at pictures and videos to see things more clearly.


As a student at Jefferson City High School, Dean was very smart. At the University of Tennessee, he was top of his class with a bachelor’s degree in engineering. He later earned a master’s degree in electrical engineering at Florida Atlantic University, in 1982.


Later inventions


Dean, along with Dennis Moeller, created a device to make things, such as printers and disks, plug into computers directly. Dean was also involved in the creation of a gigahertz chip when he worked for IBM, which is a great piece of technology that is able to do a billion calculations a second.


Dean’s amazing work helped make computers much more powerful and easier to use. The inventions he made are used in every computer today. In 2011, Mark Dean famously said that he uses a tablet instead of a computer with a monitor now, even though he invented the first colour PC monitor!


In 1996, Dean received the IBM fellow award, which made him the first African American to do so.
