Clara Hantel Brucker, 87, widow of former secretary of the Army Wilber M. Brucker, died Monday in a Hospital in Grosse Pointe, Mich. She had leukemia.

Mrs. Brucker was the author of the 1968 book, "To Have Your Cake and Eat It," which told of the years between 1954 and 1961, when she and her husband lived in Washington.

Mr. Brucker was general counsel at the Defense Department for a year before becoming Army secretary in June 1955, a post he held until 1961.

Mrs. Brucker was born in Iowa and reared in Saginaw, Mich. She studied at the Drexel Institute, Columbia University, and Hunter College. She earned a bachelor's degree in economics and a master's degree in political science at Michigan State University.

During her years in Washington, she collected antiques, became known for her photography, and was active in the International YWCA, the auxiliary of the Rainbow Division Veterans and in the Republican Ladies Auxiliary.

She also served as chairman of the endowment fund for the Soldiers, Sailors, Airmen, and Marines Club in the 1950s.

She and her husband returned to Michigan in 1961 and lived at Grosse Pointe Farms. Mr. Brucker died in 1968.

Survivors include a son, Wilber Jr., of Grosse Pointe Farms, and three grandchildren.
