Alfred Traeger

Alfred Traeger (1895 – 1980) inventor of the pedal radio
A faithful Christian, electronic tinkerer and scientific inventor, Hermann Alfred Traeger, gave the Outback, and the Royal Flying Doctor service, a way of fast contact via the innovative local sustainable technology of the Pedal-Powered Wireless which he invented.

Alfred Traeger, engineer, was born on 2 August 1895 at Glenlee, Dimboola, Victoria, eldest son of Johann Hermann Traeger, farmer, and his wife Louisa, née Zerna, both South Australian born. His German grandparents had migrated to South Australia in 1848 and his father returned there with his family in 1902.

A curious, patient, precise child, at 12 Alfred made a telephone receiver and transmitted between the toolshed and his house. He attended Balaklava Public School and the Martin Luther School before spending two years at technical high school. From 1912 he studied mechanical and electrical engineering at the South Australian School of Mines and Industries (associate diploma, 1915).

He worked for the Metropolitan Tramways Trust and the Postmaster-General’s Department. In World War I he was angered that his application to join the Australian Flying Corps was refused, even though his grandparents had been naturalized. About 1923 Traeger joined Hannan Bros Ltd in Adelaide, handling their car generator and electrical repairs. Intrigued by radio, he obtained an amateur operator’s licence and built his first pedal transmitter-receiver, later forming Traeger Transceivers Pty Ltd.
