Clark passed his high school equivalency test and entered college.

University of New Orleans, and in 1974 he earned a doctorate in
computer science at the University of Utah. He spent four years in the Navy where he was introduced
to electronics. Clark began taking night courses at Tulane
University's University College where, despite his lack of a high
school diploma, he was able to earn enough credits to be admitted to
the University of New Orleans. There, Clark earned his bachelor's
and a master's degrees in physics, followed by a PhD in computer
science from the University of Utah in 1974.
In 2018 Mr. Clark had an
