In 1969, when he took over an old-line Washington, D.C.-area construction firm that now bears his name, A. James "Jim" Clark had a growth vision that differed sharply from its founder. Decades later, the successor set the foundation that propelled George Hyman Construction Co. to become today's national industry giant Clark Construction Group, and transformed Clark himself into a billionaire philanthropist.
Clark died on March 20 in Easton, Md. of congestive heart failure at age 87, the Bethesda, Md.-based firm said.
