Horace Clowes Brinsmead (2 February 1883 – 11 March 1934) was the Controller of Aviation in Australia between 1920 and 1933.
He was born in 1883 at Hampstead, London as the son of Edgar William Brinsmead and Annie Brinsmead. He migrated to Australia around 1903, where he settled down in North Queensland, later in Tonga. When the First World War started in 1914, he joined the First Australian Imperial Force. He served and fought on Gallipoli and at Pozières.
Recovering in England after an injury in 1916 and after completing an officers course, he served in the Australian Flying Corps at its headquarters in London. The AFC headquarters was responsible for supervising the Australian Training Wing which was based in England. Brinsmead was promoted to lieutenant colonel in 1919.
After his return to Australia in 1920, Horace Brinsmead was appointed Australia's first Controller of Civil Aviation. On 8 December 1920, he married Ivy Ernestine McDonald, daughter of Charles McDonald.
In 1931, while travelling to London to negotiate for the establishment of the first air mail route between England and Australia, his plane was destroyed on takeoff at Alor Setar in Malaysia. There were no casualties and Brinsmead suffered only minor injuries. Instead of waiting for a replacement airplane, he took a commercial flight. This airplane crashed on takeoff at Don Muang Airport in Bangkok on 7 December. Five others were killed, Brinsmead survived with bad injuries but was no longer able to work. He was brought back to Australia in February 1932, officially still holding his office. Acting Controller during the following year was his deputy Edgar Johnston, until he took office in 1933.[1]
Brinsmead died in March 1934 in Melbourne, leaving one son and two daughters.
