Anthony F. Barbieri, managing editor of The Sun, said yesterday that he would retire after a 34-year career at the paper.
Barbieri, who expects to leave at the end of August, said he hopes to spend the last portion of his career teaching or giving back to journalism.
"This is the right time to leave," said Barbieri, 57. "It is sort of time to turn a page."
Timothy A. Franklin, who was named editor of The Sun in January, said he would begin a search for a managing editor immediately.
"I am determined to find the best person in the nation for the job, a superb journalist who is completely dedicated to excellence and building on the great traditions of this great newspaper," Franklin said in a memo to the staff.
He called Barbieri an "invaluable partner" and said his "commitment to the highest journalistic standards is unwavering."
"I will miss him greatly," Franklin said.
Barbieri's decision comes six months after William K. Marimow, the editor who helped lead The Sun to a Pulitzer Prize in 2002, was dismissed by Denise E. Palmer, the paper's publisher and chief executive.
Franklin assured staff members that he and Barbieri did not have a falling out.
The announcement "has a simple story line," Franklin said. "This was just a good time for Tony to take retirement."
A native of Schenectady, N.Y., Barbieri joined The Sun in 1970 after graduating from George Washington University. He spent his first six years as a reporter in the metro section and then three years in the Washington bureau.
In 1979, Barbieri became a foreign correspondent working in the paper's Moscow and Tokyo bureaus where he covered the Soviet Union's invasion of Afghanistan, the rise of Solidarity in Poland, and the ouster of Philippine President Ferdinand E. Marcos.
"I had incredible stories to cover," Barbieri said. "I had a great time covering stories that were really meaningful."
Barbieri returned to the newsroom in 1989, and worked in a variety of positions, including city editor, news editor and metro editor. He was named managing editor in 2000.
