Malcolm Guy Stewart



Malcolm Guy Stewart, 85, late of Keswick Road, Florence, SC, died at McLeod Hospice House on January 8, 2018.

He was born in Bar Harbor, Maine, on June 3, 1932, to William Dugald Stewart and Myra Elizabeth (Moon) Stewart, and attended Bar Harbor public schools. He graduated, with honors, from Virginia Tech with a Bachelor of Science in Industrial Engineering. He served in the US Navy for four years as Lieutenant, JG. He then received a Masters of Science, also with honors, from the Massachusetts Institute of Technology (MIT), Cambridge, MA.

He joined the management consulting firm of Harbridge House in Boston, MA, where he led several system design projects commissioned by the US Army for the then-new world of computer automation. Significant among those was the design of the computer-based system by which major weapon system component parts are managed and budgeted, and the management of the team that developed, tested, and implemented the system at the US Army Communications-Electronics Command (CECOM) at Fort Monmouth, NJ. The system was adopted by Department of Defense (DoD) for use by all the military services and his baseline concept of parts management and budgeting continues in use today by DoD and the Office of Management and Budgeting (OMB).

In the 1970’s, he founded his namesake firm, Stewart Associates, based in Red Bank, NJ, where he continued his systems design efforts for the US Army through CECOM and the Program Managers (PM) of major Army weapon systems. His design projects and consulting reached into the industries of Hughes Aircraft, Motorola, Raytheon, BAE, ITT and Tobyhanna Army Depot. While he led a variety of projects, he was personally involved with PM Radar’s FIREFINDER system for more than two decades. He pioneered an ‘on-line network’ system and protocol to support FIREFINDER years before the Internet we know today became available. Recognizing the technological advancement of the Internet, he led the PM Radar’s project for maximum supportability of the FIREFINDER radars by establishing database, protocol, and a cadre known as Team FIREFINDER to continue tracking and supporting the evolution of the radars. Today, most US Army major weapon systems are supported by similar technique.

Malcolm retired in 2006 and relocated with his wife, Ethel, to Florence, SC, to be near his daughter and grandchildren.

He is survived by his wife of 50 years, Ethel Brooks Stewart; his first wife, Barbara Ann Cleaves Cole, Bar Harbor, ME; and children, Sara Butterfield Stewart (Wach), formerly of Florence and now living in Portsmouth, NH; Alan MacKendrick Stewart, Florence, SC; and Duncan Cleaves Stewart, Lexington, MA. He is also survived by five grandchildren, Abigail and Beatrix Wach; Ian, Adrian, and Emma Stewart; and two step-grandchildren, Samantha and Alex Zabaneh.

Committal and celebration of life will be held in Bar Harbor, Maine, later this year.
