The president and CEO of the National Constitution Center announced Friday that he will be stepping down, effective Oct. 31.
David Eisner, who was president and CEO for nearly three years, will stay on to present the 2012 Liberty Medal to Muhammad Ali on Sept. 13 and to open the Constitution Center's exhibition about Prohibition on Oct. 19, according to a news release issued by the center Friday.
He also will assist in the search for a new chief for the center.
"The National Constitution Center has made significant progress in establishing itself as a regional and national attraction, and this is the right time for me to step aside," Eisner said in the statement. "I am very confident in the center's ongoing success, both now and in the long term." In the statement, Eisner indicated that he would be pursuing "new opportunities in both the public and private sectors."
