Richard A. Ennis, 88, a retired official of the Washington Gas Light Co., died of cancer Monday at the Sligo Gardens Nursing Home in Tokoma Park.

He had retired in 1953 as head of the tax and insurance department of the company.

Born in Prince William County, Va., Mr. Ennis grew up in Baltimore. He joined the Washington Gas Light Co. as a messenger in 1912 and later became comptroller of the firm.

A former resident of Washington and Silver Spring for many years, he had entered the nursing home just four days before his death.

Mr. Ennis was a past president of the Quarter Century Club of the Washington Gas Light Co. He belonged to the Blue Flame Masonie Club and was a 50-year member of the Washington Centennial Masonic Lodge No, 14 and the Scottish Rite Valley of Washington, Almas Temple.

He also had been a member of the Washington Board of Trade and the Oldest Inhabitants of D.C.

He is survived by three daughters, Marjorie E. Bailey, of Rockville, Barbara E. Fierstein, of New Carrollton, and Margaret G. Jordan, of Lehigh Acres, of Fredericksburg, Va.; 10 grandchildren and one great-grandchild.

The family suggests that expressions of sympathy be in the form of contributions to the American Cancer Society.
