NEW YORK (AP) - The longtime administrator of the Pulitzer Prizes is retiring.
Columbia University announced Wednesday that Sig Gissler will retire as administrator of the prizes this summer.
The 78-year-old Gissler has been Pulitzer administrator since 2002.
The Pulitzer board opened its journalism competition during that time to entries from online-only news organizations and encouraged a full range of digital components such as video and other multimedia formats.
Board Chairman Paul Tash says Gissler has been "a devoted and wise steward" of the prizes.
Gissler was editor of The Milwaukee Journal and a faculty member of the Columbia Journalism School before becoming the Pulitzer administrator. He continued to teach part-time after his appointment as prize administrator.
The Pulitzer Board has formed a committee to nominate the next administrator.
