Warren Collins Allen, 57, the corporate executive responsible for inventory at the Henry B. Gilpin Wholesale Drug Co. in Oxon Hill, died at Sibley Memorial Hospital Sunday of complications after a heart attack.

Mr. Allen moved to Washington in 1949 and worked briefly for the FBI. He joined the Gilpin company in 1951 and worked his way up from salesman through market control into the corporate offices. He had been in charge of inventory for about 15 years and held that post at the time of his death.

A native of Largo, Fla., Mr. Allen attended St. Petersburg Junior College in Florida and came to Washington in 1940 to work for the FBI. In 1943, he joined the Army and served in Europe during World War II. He then returned to Florida and studied pharmacy at the University of Florida in Gainesville.

Mr. Allen was a resident of Silver Spring and a member of the Glenmont United Methodist Church in Wheaton.

Survivors include his wife, Reid F. Allen, whom he married in Largo in 1947, of Silver Spring; two children, Sharon Gilder of Gaithersburg, and Thomas Allen of Silver Spring, and one brother, James E. Allen Sr. of Washington.

The family suggests that expressions of sympathy be in the form of contributions to the Warren C. Allen Memorial Fund, Glenmont United Methodist Church, Wheaton.
