The Black Man Who Contributed to the Invention of the Modern Computer

Mark E. Dean is an 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. He holds three of nine PC patents for being the co-creator of the IBM personal computer released in 1981.

Mark Dean, an engineer, was instrumental in the invention of the modern personal computer. He owns three out of the nine Patents which were used by International Business Machines (IBM) to produce the Personal Computer (PC).

He was born to Barbara and James Dean, in Jefferson City, Tennessee, in 1957. As a young boy, he already started to show prowess and genius in engineering. He amazed his white classmates and teachers, at the Jefferson City High School, which was an integrated school. He would always come out with straight-A grades.

He would later go on to the University of Tennessee, where he earned a Bachelors Degree in Electrical Engineering, in 1979. After his B.Sc. he went further to Florida Atlantic University, where he graduated with a Masters Degree, in 1982. He would later, during his career, obtain his doctorate in the field from Stanford University, in 1992 – this was years after his contributions to the invention of the modern PC.

After his time at Florida Atlantic University, he got hired by IBM. In 1981, at the initial stage of his time at IBM, he and his colleague invented the ISA Bus, which was meant to make the Personal Computer more efficient and durable in offices and business environments. The invention made it possible for monitors, disk drivers, printers, and scanners to be connected directly to personal computers. The picture directly below shows what the first ISA Bus looked like.

Dean’s entire career was spent at IBM. He was hired to become the chief engineer on the Personal Computer Project, with some of his early contributions being the IBM PS/2 Models 70 and 80, the Colour Graphic Adapter, and the internal architecture which allows Personal Computers to make use of peripheral high-speed devices, such as keyboards, scanners, and mouses.

After he got his doctorate from Stanford University, he returned to IBM, and he was made an IBM fellow in 1995 – this was the highest honor in the company. In 1997, IBM made him the vice president of the company, and he was inducted into the National Inventor’s Hall of Fame.

He and his team, in 1999, invented the world’s first gigahertz chip, with the power to process one billion calculations per second. Mark Dean has issued over 40 patents to date and has been honored by numerous organizations of the world. In 2001, he was elected to become a member of the National Academy of Engineers (NAE).

The life and contributions of Mark Dean are worthy of praise and teaching. His achievements and many others such as his should be thought in schools and through other forms of public information.
