David M. Bates, 88, a former president of Bates Duplicating Co. in the District, died April 6 at his home in Avon Lake, Ohio.

He had congestive heart failure, said his son, Rick Bates. Mr. Bates had lived in Arlington until moving to Ohio in 2001.

Mr. Bates joined Bates Duplicating Co., a mailing and copying firm founded by his father, as an operating officer in 1954. He served as president from 1971 until 1984, when he retired and sold the business. Its clients included Ford’s Theatre, his son said.

David McGuire Bates was born in Arlington. He graduated from Western High School in Washington in 1942 and received a bachelor’s degree in history from George Washington University in 1946.

Before joining the family business, he was an elementary teacher and principal with Fairfax County Public Schools.

He was a volunteer trail overseer, historian and archivist with the Potomac Appalachian Trail Club and sang with groups including the Singing Capital Chorus and several Washington-area church choirs.

His wife of 53 years, the former Dorothy Mathews, died in 2011. Survivors include his son, Rick Bates of Avon Lake, and three grandchildren.
