Arthur was born at Bondi on 27 October 1894, the eldest son of William Stewart Mowle and grandson of Mr A K Mackenzie of “Boonara”, Bondi.1
After working as an architect, in 1916 he enlisted in the AIF and underwent training as a pilot. His flying exploits ended in July 1917 when, having been severely wounded, he was shot down in a dogfight over France.2 After several months of hospital treatment he was repatriated and discharged early in 1918.
Rebuilding his life, he married Adrienne Elsie Genty in Sydney later that year. The reception was held at the prestigious Adams Hotel and featured a wedding cake adorned with a model aeroplane.3
Arthur’s architectural practice appeared to flourish. However, in June 1931 he relocated to a dairy farm at Barrington, near Gloucester, where he concentrated on the breeding of Australian Illawarra Shorthorn cattle.4
By 1934 his architectural practice was again in full swing and he designed many buildings in and around Gloucester including the Street & Parish shops, a grandstand for Gloucester Park, additions to Gloucester Dairy Company and a Presbyterian Church at Barrington.5
Around 1936 he moved back to Sydney and seems to have worked as an architect in government employ in his later years.6 He died in 1987 having been predeceased by his wife in 1981.7
