Angwin collapsed and died in an Adelaide store. He was buried at Centennial Park Cemetery.
The Premier, Sir Thomas Playford said of him:
"I cannot pay too high a tribute to the work which Mr. Angwin accomplished for South Australia. He was a public service officer who had the highest ability. He combined outstanding technical knowledge with a pronounced gift for administration. He was one of the foremost citizens of South Australia and his loss will be deeply regretted by everybody who came in contact with him and by the State which has gained much from his work. The Government extends its sympathy to his wife and family in their loss."
Sir Malcolm McIntosh, who was associated with him for twenty years said:
"Mr. Angwin's life was the epitome of wisdom, dignity and service. Great as were his public services as Engineer-in-Chief in the Electricity Trust and the Harbors Board, they were not greater than his capacity to attract loyal devotion and support from all who served with him. He was always the first to acknowledge this support. He had great scientific gifts, but these did not transcend his other attributes. The State has been enriched by his services ... Those who had the privilege of fellow scholarship and friendship will also revere his memory and with his family mourn their loss."

Family

Enid Angwin ( – ) married Dr. Richard Bennett ( – ) on 11 February 1955
