John C. Halliwell ’50

John C. Halliwell ’50, of Barrington, R.I.; Nov. 21. After serving in the U.S. Army Air Forces during World War II, he graduated from Brown and joined the Grinnell Corporation in Providence learning building design for mechanical systems and equipment. In 1954 he left Grinnell and founded Halliwell Engineering Associates (HEA), which grew to include plumbing, HVAC, and electrical systems design. Two of his sons later joined the company and added civil, structural, and environmental engineering services. In 1987, Walt Disney World hired HEA to be its lead engineer for environmental engineering and that relationship continues today. Throughout his career he owned several powerboats and sailboats and enjoyed sailing between Newport and Ft. Lauderdale. He also enjoyed playing the ukulele and created the Wicky-Wacky Ukulele Club, where he taught people how to play and made many new friendships. At age 90 he wrote the story of his time in the Air Force during World War II, entitled Flying Nightmare and published by Amazon Publishing in 2018. He is survived by his wife Diane and three sons.
