History and use
This theodolite was owned by Sir Augustus Charles Gregory. It was held by the Museum of Microscopy at the University of Queensland until that collection was donated to the Queensland Museum.

Sir Augustus Charles Gregory was appointed as Queensland’s first Surveyor General, holding the post from immediately after secession in 1859 until 1875. Gregory was known for both his exploring (the last major expedition he led being a failed attempt to find Leichardt) and his surveying.

As Surveyor General for Queensland, he surveyed part of the newly established Queensland New South Wales border. He later became geological surveyor for south Queensland. Appointed as one of the foundation trustees of the Queensland Museum and the first chairman of the Board of Trustees, he continued serving on the board from 1876-99. He also donated a range of material including mineral samples.
