Maj. Gen. Robert W. Hasbrouck, commander of the United States Seventh Armored Division in Europe in World War II, died Monday at Georgetown University Hospital in Washington. He was 89 years old.

In 1945 General Hasbrouck was awarded the Silver Star for gallantry in action when he personally directed his division's operations in Belgium to halt the German drive on Liege in the Battle of the Bulge. The division held a salient around St. Vith against four German divisions for six days, allowing the First Army to establish new defensive positions.

Before taking command of the division in 1944, General Hasbrouck was deputy chief of staff under Gen. Omar N. Bradley, then commander of the First Army Group in Europe.

General Hasbrouck retired in 1947. He received the Distinguished Service Medal, the Legion of Merit and the Bronze Star for valor, and was also decorated by the Governments of Belgium and France.

He was born in Kingston, N.Y. His family, of French Huguenot ancestry, had lived in the area for generations. He graduated from the United States Military Academy in 1917, and was a captain of artillery in World War I. He is survived by his wife, Marjorie Nightingale Hasbrouck; a daughter, Marjorie H. Deschodt, of Paris; a son, Robert W. Hasbrouck, of Summit, N.J., and four grandchildren.
