Frank Skjellerup


John Francis Skjellerup was an Australian amateur astronomer who spent two decades working as a telegraphist in South Africa.
His father Peder Jensen Skjellerup was Danish and died when he was young; his mother was Margaret Williamson, born in England. He was born in Cobden, Victoria, Australia, the tenth of thirteen children. His youngest brother, George Skellerup, became a successful industrialist in New Zealand.
Trained as a telegraphist, he went to South Africa when that country needed telegraphists after the Second Boer War; 18 telegraphists left Australia on 21 February 1900 on the SS Australasian for Cape Town. Apparently he was an excellent golfer as well as an astronomer. He married Mary Peterson and returned with her to Australia in 1923 where they settled in Melbourne; she died in 1950 and there were no children. He lived in the Melbourne suburb of Oakleigh and died in his home town on 6 January 1952.
He took up astronomy in South Africa. There was no family history in science, let alone astronomy, and Skjellerup was unable to establish a family connection to the Danish astronomer Hans Schjellerup. In 1912, he was a foundation member of the Cape Astronomical Association. He discovered or co-discovered various comets in both South Africa and Australia, including the periodic comet 26P/Grigg–Skjellerup in South Africa and the very bright Skjellerup–Maristany in Australia. In addition to comets, he was also a variable star observer.
