Robert L. J. Ellery - Career

Career

Ellery sailed for Victoria in 1851 attracted by the discovery of gold, and is stated to have practised as a physician at Williamstown, Victoria. If so it could only have been for a very short period, as in 1853 the Victorian government decided to found an astronomical observatory at his urging, and in July 1853 Ellery was placed in charge of it.

The Victorian government observatory was at first on a very modest scale, being housed in a small two-roomed cottage at Williamstown, and the only instruments were a sextant, an artificial horizon and a marine chronometer. However, by March 1854, a 30-inch transit instrument, a good astronomical clock and a time-ball apparatus had been added, and a few meteorological instruments were also obtained.

The work to be done was not heavy, and Ellery also undertook for a time the duties of storekeeper of the marine depot. In 1856 he began a geodetic survey of Victoria which was not completed until 1874. At the beginning of 1858 the government founded another observatory known as the magnetic observatory on Flagstaff Hill, West Melbourne, under a distinguished German scientist, Georg von Neumayer, who had applied for a site in the Domain south of the Yarra without success. Both Ellery and Neumayer found that the sites given them were not suitable for their work, but it was not until 1863 that a move was made to the Domain. Edward John White, an able astronomer, was added to Ellery's staff in May 1860, and several valuable catalogues of stars were prepared and published. In 1868 a new telescope was sent out from England but the results obtained with it were unsatisfactory. Ellery resolved the issues he had with the telescope by applying his mechanical ability to the problems involved. At the end of 1890, another telescope arrived and Ellery began a new important piece of work, the preparation of the share allotted to Melbourne of the astrographic chart. He retired in 1895 and was succeeded by Pietro Baracchi.
