Robert D. van Roijen, 73, a cattle farmer in Warrenton, Va., and a retired official of the Central Intelligence Agency, died Wednesday at his Washington residence. He had emphysema.
Mr. van Roijen was born in London, where his father was stationed, as a Dutch diplomat. He earned a doctorate in law at the University of Utrecht in The Netherlands in 1936 and moved to the United States the same year.
He moved to New York City, where he studied journalism. Two years later, he married the former Hildegarde Graham. The couple bought St. Leonard's Farm in Warenton and that was Mr. van Roijen's principal residence for the rest of his life.
He became a U.S. citizen in 1942 and was an intelligence officer in the Army Air Corps during World War II. He saw service in North Africa and Europe.
In 1948, he joined the CIA. He was stationed in Germany for some time in the early 1950s. The rest of his career was in Washington. He retired in 1962.
In 1964, he purchased Robert B. Luce Inc., a Washington publishing firm. He sold it in 1978.
Mr. van Roijen's survivors include his wife, of Warrenton; four sons, Robert Dudley Jr., of Orlando, Fla., Peter P. and Christopher T., both of Warrenton, and David M., of Charlottesville; two daughters, Valaer Goodrich and Laura W. de Vogel, both of New York City; a brother, Herman, who was the Dutch ambassador in Washington from 1947 to 1961, of Wassenaar, The Netherlands, and four grandchildren.
The family suggests that expressions of sympathy be in the form of contributions to Fauquier Hospital or to the Highland School, both in Warrenton. Mr. van Roijen was the chairman of the board of both institutions.
