The American Bankers Association has announced the appointment of Donald G. Ogilvie as executive vice president. Ogilvie will leave his position as vice president in charge of government relations and communications for Celanese Corp. in New York to take the top ABA staff post next month.

Ogilvie succeeds Willis Alexander, who will retire next month after serving as ABA executive director since 1969.

Ogilvie worked as an associate dean and lecturer at Yale University until 1980, when he joined Celanese Corp. From 1973 to 1977, he served as associate director of national security and international affairs in the Office of Management and Budget, and from 1967 to 1969 he worked in the Department of Defense.

In making the announcement last week, ABA President J. G. Cairns Jr. said, "We are honored and delighted to have Don Ogilvie, an executive with credentials and reputation of the highest caliber, to lead our organization along the challenging path that lies ahead for this country's banking industry."

ABA also has promoted Jeffrey S. Owen, who has served as director of the ABA state association division, to executive director of the association's banking organizations group. Owen will develop policy and programs for the group's community banker members and state bank association members as well as for the National BankPac Committee, the ABA's political action committee.
