Ruth Sawyer Yeuell, 64, a former Washington resident and employe of the Washington Psychoanalytic Institute who served as a captain in the Women's Army Corps in Europe in World War II, died Sunday at Columbia Presbyterian Hospital in New York City after a heart attack.

Mrs. Yeuell, who lived with a daughter in Indianapolis, was visiting relatives when she was stricken.

She was born in Sacramento, Calif., and graduated from Stanford University. She joined the WACs in 1942 when that branch of the service was established. She was commissioned a lieutenant and later served in England, France and Germany.

In 1946, she moved to Washington. From 1957 to 1964, when she left this area, she was a secretary at the Washington Psychoanalytic Institute. She later lived in New York and North Carolina and in 1975 moved to Indianapolis to live with a daughter, Michel.

Her marriage to Army Col. Donovan P. Yeuell Jr. ended in divorce.

In addition to Michel Yeuell, survivors include another daughter, Susan Yeuell of Chapel Hill, N.C.; a son, Paul, of San Francisco; a brother, Dr. W.H. Sawyer of Scarsdale, N.Y., and two sisters, Mrs. Wallace Carroll of Winston-Salem, N.C., and Mrs. Roger W. Howell of Chapel Hill.

The family suggests that expressions of sympathy be in the form of contributions to the Heart Fund of the American Heart Association.
