Summary

Raymond Cottam Allsop was an inventor and pioneer radio engineer. He was involved with radio in Australia from its earliest incarnation and later in life was a vocal advocate for the introduction of television.

Details

In the early 1920s he conducted experimental transmission work for 2BL in the lead up to their launch as Australia's first live radio station.

On his private station 2YL Allsop conducted bold experiments, such as the broadcast of the Big Ben live from London in 1927 and the charting of (Sir) Charles Kingsford Smith's historic flight in the Southern Cross in 1928.

In 1929, Allsop demonstrated his 'Raycophone' sound synchronisation system for movie theatres which, at a tenth of the price, beat the American competition out of the market and was installed in 375 cinemas across Australia.

During both World Wars Allsop served as a naval radio engineer, first as senior wireless telegraph operator in transports (1916-18) and then as engineer lieutenant (1940-43).
