Percy Lee Burdette, 75, a retired Treasury Department employe who was active in church affairs, died of emphysema Sunday at Mount Vernon Hospital in Alexandria.

He joined Treasury as a messenger in 1920, and worked as a research analyst with the Office of the Secretary for 35 years before retiring in 1962.

Mr. Burdette was an honorary deacon of the First Baptist Church of Alexandria. He also was a member of the church's tellers' committee, a charter member of the Open Door Baraca Bible Class, and had managed First Baptist's softball team.

He was a charter member of the Alexandria Church Men's Bowling League and had played baseball and softball with a number of area teams, including the Treasury Department's baseball team.

Mr. Burdette was born in Woodbridge, Va. He came to this area to work for Treasury and had been a resident of Alexandria for the past 45 years.

Since retiring from the Treasury Department, he had worked in the insurance business with his wife, Irma.

In addition to his wife, of the home; he is survived by a daughter, Gerry Murphy, of Alexandria; two brothers, William Jr. and Clarence R., both of Woodbridge; four sisters, Pearl Gorham and Ruth Mitchell, both of Alexandria; Florence Simpson, of Palm Bay, Fla., and Elizabeth Sullivan, of Woodbridge, and two grandchildren.

The family suggests that expressions of sympathy be in the form of contributions to the First Baptist Church of Alexandria.
