Walter Clement “Walt” Nason, Jr., 91, passed away peacefully at his home in Arlington, Massachusetts, surrounded by his family on Jan. 7.

Born in 1924 in Dorchester, he was the son of Vera Guild Nason and Walter C. Nason. Walter is survived by his beloved wife of 65 years, Charlotte Ann (Collyer), and his four children.

Walt was raised in South Weymouth and Braintree, MA, and graduated as valedictorian from Thayer Academy in 1941. From there he went to MIT where he earned a BS in Chemical Engineering in 1945 and a MS in Mechanical Engineering in 1949. He then worked for the US Air Force at Wright-Patterson Air Force Base in Dayton, Ohio, on oxygenating pilots at high elevations.

Following Wright-Patterson, Walt worked for Cambridge Corporation, an Arthur D. Little affiliate, where he and two others developed a patented vacuum jacketed container, designed to carry liquid oxygen for use in aircraft.

Entering the gases industry

Walt then began a long and satisfying 45-year career as Chief Design Engineer at Process Engineering, Inc. (now part of Chart Industries, Inc.), where he designed cryogenic storage and transport vessels. He thoroughly enjoyed his career in all respects, particularly the good friendships made with colleagues and customers. He was very active for many years with the Compressed Gas Association, chairing the old Cryogenic and Low Temperature Committee and participating on several others.

Walt was an early adopter of computers and was a self-taught programmer. Many remember his contents chart programs and other design-related programs.

A life of learning

Walt also thoroughly enjoyed his children, grandchildren, photography, biking, camping, boating, and traveling. He was a lifelong student of everything: technology, history, and current events. He loved to learn.

Many CGA and industry colleagues have continued to ask about Walter over the years and always had a kind word to offer – and hopefully received one in return. His spirit and passion for the industry will be missed.
