William F. Childs III, a retired engineer who was an early salesman of do-it-yourself cement products, died of complications from heart disease April 23 at his Towson home. He was 95 and lived for many years in Stoneleigh.
Born in Salisbury, he was a 1936 graduate of the Mercersburg Academy in Pennsylvania and earned a civil engineering and business administration degree from the Johns Hopkins University, where he was lacrosse team manager.
He joined the old Glenn L. Martin Co. in Middle River. According to an autobiographical sketch, he was initially assigned to a survey party for what is now Martin State Airport. He later was an inspector for a Martin assembly plant where Navy patrol bombers were built. During World War II, he was a member of the Drivers Corps of Baltimore County Civilian Defense.
In 1947, he joined the old Harry T. Campbell Sons Corp. and worked in the first sales of a new product, Sakrete, which was mixed cement sold in paper bags marketed to the consumer retail market. He sold the product in Virginia, West Virginia, Washington and parts of Maryland.
He was later named manager of the Campbell Marriottsville quarry. In 1968, he was appointed assistant to the president of the Campbell-Grove Division of Flintkote Stone Products. He retired in 1979 and remained a consultant to Genstar Corp. and the Redland Corp.
He was also a lobbyist at the Maryland General Assembly and remained active in that field until he retired again in 1989.
Mr. Childs was a founder of the Maryland Aggregates Association and a vice president of the Baltimore Metropolitan Chapter of the Associated Builders and Contractors.
A past president of Timonium Rotary Club, he was a Mason and belonged to the Boumi Temple and was a life member of the Royal Order of the Jesters.
Mr. Childs liked to sail and raced Star boats. He was a 70-year member of the Annapolis Yacht Club. He also sailed the Chesapeake Bay on a cabin cruiser, the Sand Bill.
Services will be held at 11 a.m. Friday at Trinity Episcopal Church, 120 Allegheny Ave. in Towson, where he had served on the vestry.
