Sir Talbot Sidney Duckmanton CBE (25 October 1921 – 12 June 1995) was an Australian broadcaster and radio and television administrator. As General Manager of the Australian Broadcasting Commission he oversaw the advent of colour television, ABC Classic FM and Triple J.
He began his career as a cadet announcer at the ABC in Brisbane in 1939 and had a wide ranging career working as a news announcer and sporting broadcaster. During World War II Duckmanton saw active service as a pilot and was later a war correspondent. From 1952 until 1954 he was the Assistant Manager of the Brisbane office.
He was Deputy General Manager of the organisation 1964-65, and General Manager from 1965 until his retirement in 1982.
It was rumoured and is widely believed that Sir Talbot Duckmanton was responsible for choosing the ABC post office box number 9994 in recognition of Sir Don Bradman's batting average of 99.94. However this only became the ABC's box number in 1983, after Duckmanton's retirement. There is as yet no published evidence that the connection between the box number and Bradman's average was intentional.
In a story published on 4 October 2004 on the ABC Brisbane (612AM) website, a task was set to find a name for the mascot of ABC Brisbane. In an article on the same website published on 27 October 2004, 'Talbot' (in honour of Duckmanton) was declared the winner over the other candidate 'Gabba' (a reference to the nickname of the Brisbane Cricket Ground in the suburb of Woolloongabba).
He married Florence Simmonds in 1947 and had four children, Christine, Susan, Craig Talbot and Kim.  Florence died in 1978. The following year he married Janet Strickland, the Australian Chief Censor, but they separated two years later. His third marriage was to Carolyn Wright, an Englishwoman. This marriage also lasted only two years. He later went back to Janet Strickland.
