Rockwood names former US ambassador to board

PRINCETON, N.J. (AP) -- Rockwood Holdings Inc., which makes chemicals and pigments used in manufacturing, said Wednesday that Alejandro Wolff, a former U.S. ambassador to Chile, has joined its board of directors.

Wolff also will serve on the board's compensation and corporate governance and nominating committees.

"His extensive and distinguished background in the service of the United States government brings a significant new perspective and set of skills to our board," said Seifi Ghasemi, Rockwood's chairman and CEO, in a statement.

Wolff retired from the Department of State on Aug. 23. Before being named ambassador to Chile in 2010, he was ambassador and deputy permanent U.S. representative to the United Nations. He has worked at the Department of State since 1979.
