This square honors Brooklyn resident Harold P. McDonald (1898-1934). Private McDonald served in the United States Field Artillery during World War I in France. His comrades reported that McDonald was one of the most popular men in his company. Although wounded in action, in 1919 he returned to the United States in relatively good health. Together with a number of other veterans he knew during World War I, McDonald joined the Kings County Lighting Company.
Eventually, McDonald rose to the position of Advertising Manager of the firm. The men subsequently formed American Legion Post 261. McDonald’s clever mind and winning personality made him exceptionally well liked. In 1934 McDonald developed a duodenal ulcer, had a gastrectomy (removal of portions of the lower stomach and upper small intestine) at St. Mary’s hospital, and died shortly thereafter of post-operative shock.
