Edward C. Retterer, 33, who drowned in a boating accident in the Potomac River June 15 when a violent storm struck the Washington area, was the general marketing manager of a microfilm company in Arlington.

Mr. Retterer was born in Chicago and grew up in Darien, Conn. He graduated from the University of Notre Dame and then served two years as a lieutenant in the Army Quartermaster Corps.

He moved to the Washington area in 1976 from Boston to become marketing manager of the Computer Microfilm International Corp.

Retterer lived in Springfield and Annandale before moving to Alexandria, where he lived at the time of his death.

He was a member of the National Microfilm Association and the Notre Dame Club of Washington.

His marriage to the former Lin Karl ended in divorce.

Survivors include two sons, Chapman and Jason, and a daughter, Emily, all of New York City; his parents, Ray and Julia Retterer, of Atlanta, two brothers, Bill, of Atlanta, and Josh, of Venice, Calif., and one sister, Ginger Retterer of Atlanta.

The family suggests that expressions of sympathy be in the form of contributions to the Notre Dame Club of Washington Scholarship Fund in Mr. Retterer's name.
