Dr. Mark Dean was instrumental in the development of the Personal Computer while working at IBM. Currently he holds 20 patents, including 3 of the original 9 IBM Personal Computer patents.

He is perhaps most famous for his invention of a " Microcomputer System with Bus Control Means for Peripheral Processing Devices", which is Patent Number(s) 4,528,626. He co-invented this device with Dennis Moeller. Their invention allows us to use plug-in (commonly referred to as "plug and play") subsystems and peripherals like disk drives, video gear, speakers, and scanners.
