Walter C. Crouse, 55, a former PBX installer-repairman with the C&P Telephone Co. and later a doorkeeper for the U.S. Senate, died Monday at Johns Hopkins Hospital in Baltimore after undergoing open heart surgery.

He retired in 1973 after 31 years of service with the C&P. He then worked at the Senate until retiring a second time last January.

Mr. Crouse was born in Washington and was a graduate of Central High School. He served in Europe with the U.S. Army Signal Corps in World War II.

He served three terms as commander of the Silver Springs Memorial Post 2562, Veterans of Foreign Wars, and held various offices in the Military Order of the Cootie, the honor degree of the VFW. He was supreme surgeon of MOC at the time of his death.

Mr. Crouse was active in the fund-raising affairs of the Wheaton Rescue Squad, the Laurel Children's Center, the Great Oak Children's Center and the Country Entertainers and Musicians Benevolent Association (CEMBA). He was a member of Potomac Lodge No. 5 of the Masons.

He is survived by his wife, Evelyn, of the home in Silver Spring; a daughter, Barbara Anne Crooks, of Silver Spring; a son, Richard Wayne, of Rockville, and two grandchildren.

The family suggests that expressions of sympathy be in the form of contributions to the American Heart Association.* CAPTION: Picture, WALTER C. CROUSE
