Henrietta E. Langer, 74, a retired employe of the old Federal Housing Administration who was active in church, service and retirement organizations, died Tuesday of renal failure at Doctors Hospital here.

Miss Langer joined the FHA in about 1935. She was a secretary in the underwriters division when she retired about 1965.

A native of Washington, she lived here most of her life. She was a member of St. John's Episcopal Church at Lafayette Square, where for many years she supervised the preparation and distribution of the palms on Palm Sundays.

Miss Langer also was active in St. John's Business and Professional Women's Guild. She served as the Guild's bazaar chirman for a number of years and represented the Guild on the church's Women's Council.

She was active in the International Order of St. Luke the Physician, a nondenominational organization of clergy and laymen seeking to restore the bibical concept or religion in healing. In addition, she was active in the retirement program at St. Margaret's Episcopal Church and in the American Association of Retired Persons and the Wesley Heights Friendship Chapter No. 1261.

Miss Langer also worked as a volunteer with the Salvation Army and with the League of Republican Women.

Surviviors include a sister, Elsa L. Sandusky, of Washington, and two brothers, Hugo H. Langer, of Silver Spring, and Clayton W. Langer, of Chevy Chase.

The family suggests that expressions of sympathy be in the form of contributions to St. John's Episcopal Church at Lafayette Square.
