David Thomas Worrall (18 June 1894 – 12 April 1968) was an Australian journalist, radio station manager and soldier.
Worrall was born in Castle Hill, New South Wales and died in St Kilda, Victoria.
3DB commenced broadcasting in 1927 under the ownership of the Druleigh Business and Technical College Pty Ltd, hence the DB call-sign.
He was responsible for introducing many big-budget programs covering all forms of broadcastable material which, inter alia, made 3DB the top station in all Melbourne radio surveys for many decades.
In 1929, he married Kathleen Zoe née Norris at the Independent Church, Collins Street, Melbourne.
