In a news release, Dean David F. Levi said the Stars intend the gift to inspire additional contributions from the school’s alumni and friends.
Stanley Star is a member of the law school’s class of 1961.
"Stanley Star is one of the great business entrepreneurs of his generation," Levi said. "By designating this gift as a challenge to others, he and Elizabeth are demonstrating that same creativity and leadership, but this time in the area of philanthropy."
The Stars have made other multimillion dollar gifts to Duke over the years. Stanley Star is the former principal of Cliffstar Corp., which is one of the country’s leading private-label juice manufacturers. He sold the company last year.
