James B. White was named director of corporate marketing at Bridgewater Associates Inc., Westport, Conn. Mr. White was a global partner and team leader of corporate, endowment and foundation sales at INVESCO Institutional, New York, and was a member parent AMVESCAP's investment committee. It could not be learned by press time whether he was replaced. His role as the second corporate marketing director at Bridgewater is new; the first director of corporate marketing, Jeff Growney, left the firm unexpectedly this month, said Bill Mahoney, director of global marketing. No decision has been made on a replacement for Mr. Growney, Mr. Mahoney said.
