Edith Martin, 82, wife of Charles Martin, the retired headmaster of St. Albans School for Boys and a canon of the Washington Cathedral, died Oct. 19 at their home in Bethesda.

Mrs. Martin had emphysema and diabetes.

Mrs. Martin was born in Philadelphia and attended high school there. Her husband grew up in the same South Philadelphia neighborhood as she, and they had known each other since early childhood, almost 80 years.

They were married in 1934, and continued to live in the Philadelphia area until 1942, when they moved to Burlington, Vt., where Canon Martin served at St. Paul's Church.

They came here seven years later, when Canon Martin became headmaster at St. Albans and a cathedral canon.

From 1949 until 1977, when her husband retired as headmaster, she discharged a variety of informal responsibilities associated with the school's religious and social events. These included entertaining students at dinners at the couple's home, obtaining flowers for the altar at chapel services and seeing to refreshments at dances.

She was a member of the Washington Cathedral and had been a member of its Altar Guild.

For a number of years in the late 1960s and 1970s, Mrs. Martin and her husband spent summers in Bay Head, N.J., where Canon Martin served as rector of a church while school was out.

Survivors include her husband; two sons, Peter, of Baltimore, and Charles Jr., of Bethesda; a daughter, Elizabeth McConnell of Mount Kisco, N.Y.; a brother, James Sturges of Philadelphia; and seven grandchildren.
