Veteran Washington area banker and trust officer David G. Curry has been named to open the new Washington office of Bessemer Trust Co., a New York-based investment management company.

Curry was a senior executive specializing in regional banking, marketing and trusts with Virginia National Bank. When Virginia National merged with First and Merchant Corp. to form Sovran Financial Corp., he was appointed trust executive officer.

Bessemer's move to Washington, with Curry at the helm, represents another milestone in the company's decade-old efforts to expand into new regions and increase its services beyond what they traditionally have been.

From the turn of the century until the 1970s, Bessemer's only business was managing the family holdings of one of the great steel barons, Henry Phipps. Phipps, a partner of Andrew Carnegie in the Pittsburgh-based Carnegie Steel Co., formed Bessemer Trust in 1907 to manage the trusts created for his five children after the company was sold to J. P. Morgan to form U.S. Steel Corp.

In the early 1970s, Bessemer began to seek and accept clients unrelated to Henry Phipps. With offices in New York and Florida in addition to its original New Jersey office, the company currently manages about $3.8 billion in investments ranging from stocks and bonds to real estate and oil and gas, about one-third of which are Phipps family holdings.

Already, the company manages about $100 million in assets in the Washington area, said John R. Whitmore, the company's president and chief operating officer.

Bessemer manages the pension plan for B. F. Saul & Co., the pension and capital funds for Kiplinger Washington and the alumni fund for the U.S. Naval Academy.

Bessemer also manages the personal investments of White House Chief of Staff and former Treasury secretary Donald Regan, according to his disclosures.

Bessemer, which prides itself on serving a "select clientele" on a personalized basis, was attracted to Washington because of "the area's rapid growth, our familiarity with potential clients in the market and because we think there is a real potential for our types of services," said Whitmore.

Both Whitmore and Robert C. Elliott, Bessemer Group's senior vice president, were senior executives in the trust division of American Security Bank until 1975, providing another link to the Washington area. PROFESSIONAL SERVICES
