Early life

O'Callaghan was born in Melbourne in 1933.[3][4]

Career

O'Callaghan's career in radio started in 1951 when he joined 2SM as an office boy, aged 17. He did his first on-air work within a few weeks. This began what the Daily Telegraph newspaper called "one of the most distinguished careers in the history of Australian broadcasting".[4] Early in his career, in the 1950s, he was notable for his exclusive coverage[2] of the Cold War defection that became known as the Petrov Affair.[1][5] He joined 2UE in 1956, where he was known for his long running, and ratings winning, breakfast show. He stayed with 2UE until retirement in 2003, then had a short time at 2KY during Kerry Packer's ownership of 2UE. He moved back to the mid north coast of NSW where he continued to work at 2MC.[2]

Awards

O'Callaghan became a Member of the Order of the British Empire (MBE), was named Father of the Year, and won the Queen's Jubilee Medal.[4] He was an Australian Commercial Radio Awards Hall of Fame inductee in 2004.[2][6]

Later life

O'Callaghan and his wife Dorothy lived at Wauchope, New South Wales, on the NSW Mid North Coast, near Port Macquarie.[2]

gollark: Maybe someone actually *has* been insane enough to make GCC able to compile to LLVM, who knows.
gollark: Oh, right. That would have been easier than doing it by hand.
gollark: Did you just randomly decide to calculate that?
gollark: Well, you can, or also "it would have about the same mass as the atmosphere".
gollark: Wikipedia says that spider silk has a diameter of "2.5–4 μm", which I approximated to 3μm for convenience, so a strand has a 1.5μm radius. That means that its cross-sectional area (if we assume this long thing of spider silk is a cylinder) is (1.5e-6)², or ~7e-12. Wikipedia also says its density is about 1.3g/cm³, which is 1300kg/m³, and that the observable universe has a diameter of 93 billion light-years (8.8e26 meters). So multiply the length of the strand (the observable universe's diameter) by the density of spider silk by the cross-sectional area of the strand and you get 8e18 kg, while the atmosphere's mass is about 5e18 kg, so close enough really.
