Alfred Traeger

From 1912, aged 16, he spent three years at the South Australian School of Mines and Industries, studying mechanical and electrical engineering, earning an Associate Diploma.

[3] He first worked for the Metropolitan Tramways Trust and the Postmaster-General's Department, but his application to join the Australian Flying Corps in World War I was refused.

Over time, emergency call systems linked country-dwellers with hospitals, and sets were used by the School of the Air, doctors, ambulances, councils, taxis, airlines and ships.

[1] His first workshop was in the eastern suburb of Kensington Gardens, in 1937 moving to a larger premises at 11 Dudley Road, Marryatville, where it continued to function until his death in 1980.

On 2 August 1956 he married a young widow, Joyce Edna Mibus, née Traeger (no relation), with whom he had a son and another two daughters.

[1] At the Traeger Park sports field in Alice Springs, a plaque and the Royal Flying Doctor Service aeroplane commemorate him.

[7] A plaque marks the site of the Traeger workshop at 11 Dudley Road, Marryatville, commissioned by the Kensington & Norwood Historical Society in 1998.

[3][8] In 1999, the Wakefield Regional Council in South Australia commissioned a sundial and plaque to be placed at the southern entrance to Balaklava.
