Herman G. Lauten, 76, a Washington lawyer and retired bank executive, died Thursday at Sibley Memorial Hospital after apparently suffering a heart attack.

He was with the National Savings and Trust Co. for 43 years before retiring in 1972 as a vice president and trust officer. Since then he had practiced law with the firm of Jackson, Campbell and Parkinson.

Mr. Lauten was born in Washington and graduated from Georgetown University Law School.

He was a former president of the Reciprocity Club and a former chairman of the fiduciary section of the D.C. Bankers Association. He belonged to the D.C. and American Bar associations, and the Kenwood Country Club.

An active layman in the Roman Catholic Church, Mr. Lauten was treasurer of the St. Vincent de Paul Society, a former president of the Curley Club, a director of the Catholic Youth Organization and a member of the John Carroll Society.

He is survived by his wife, Mary Healy Lauten, and a daughter, Margaret, of the home in Washington; a son, Robert, of Washington, and a sister, Dorothy L. Wilding, of Washington.

The family suggests that expressions of sympathy be in the form of contributions to the Catholic Youth Organization or to St. Ann's Infant Home.
