The Evening Star – January 10, 1958
Colonel Arthur R. MacLean, USA (retired), former teacher and post engineer at Fort Belvoir, died yesterday at Walter Reed Hospital of cancer. He was 54.
Colonel MacLean’s last assignment was in the engineers branch of the headquarters command of Supreme Headquarters Allied Powers Europe (SHAPE) in Paris. He served there from August, 1955 to March, 1956, when he learned he had cancer and returned to Walter Reed for treatment.
From 1952 to 1955 he was on staff and faculty of the engineering school at Fort Belvoir, and then became post engineer. Before that he served as post engineer of the Ryukyus Command, Okinawa, from 1950 to 1952.
The engineer officer first came to Washington when he was called to active duty in 1940. he was assigned to the office of Chief of Engineers, specializing in procurement. After serving in that office from 1940 to 1945, Colonel MacLean was assigned to the office of the Army and Navy Foreign Liquidation Commission, with headquarters in Cairo, Egypt.
Following his tour of duty in Africa and the Near East, Colonel MacLean returned to the United States as a post engineer at Fort Jackson, SC where he served during 1948 and 1949 before going to Okinawa.
While stationed here, Col. MacLean took flying lessons when off duty and qualified as a pilot of small aircraft.
He was a 1925 graduate of Massachusetts Institute of Technology, receiving the degrees of bachelor of science and civil engineer. Shortly after his graduation, he became a civil engineer on the Cape Cod Canal and qualified as a reserve officer in the United States Corps of Engineers. He worked on the So-canal for about 10 years before being called to active duty.
He was active in Masonic circles and was a member of Eliot Lodge, A.F. and A.M., Jamaica Plain, Mass, the heroes of ’76 and the Knights Templar of Seattle, Washington.
He is survived by his widow, the former Bernadine Tuckey, of the home address, 510 Juniper Lane, Falls Church, Va. Of course his wife has also died since then and is buried beside him in Arlington National Cemetery.
Michael Robert Patterson was born in Arlington and is the son of a former officer of the US Army. So it was no wonder that sooner or later his interests drew him to American history and especially to American military history. Many of his articles can be found on renowned portals like the New York Times, Washingtonpost or Wikipedia.
