George Thomas Light (1820 – 24 January 1896), commonly referred to as G. T. Light, was an organist, instrument-maker, and architect in the early days of the British colony of South Australia. History Light was born in England in 1820, a son of music teacher Thomas Light, and christened at St Andrews Church, Clifton, on 18 September 1820. He was employed in the fields of musical instrument maker and technician, optician, modeller and engineering draftsman, as well as being a more than competent keyboard player. He emigrated to South Australia, ship unknown, arriving in 1848 or early 1849. He married Marian Wilson in September 1850 at St Matthew's Church of England, Kensington; they would have six children, of whom four survived infancy. He worked as a piano tuner and foundry draftsman in Adelaide. By another account, Light was born in 1838, was employed as a musical instrument maker and draftsman at a foundry in Bristol, England, before emigrating to South Australia around 1854 and died in 1911. None of these dates stands scrutiny. Light joined the Colonial Architect’s office in 1856 as a temporary draftsman, made a permanent appointment on 1 January 1857. He became assistant architect when Edward John Woods was appointed Architect-in-Chief in 1874. In 1879 Light took leave of absence, joining J. A. Hornabrook in a partnership, with offices in Santo's Building. Light's wife died in 1882, and he left the Department in 1883. In 1884 he joined in partnership with the newly-arrived R. G. Holwell (died 1906) as Light and Holwell, at the Old Exchange. The partnership was dissolved in August 1884 and Light moved to Western Australia, where his sons had settled. Architect Government Light designed the royal coat of arms ornament on the Treasury building designed by Edward A. Hamilton in 1858. In 1859 Light designed the court house and police station at Goolwa. He was also credited with the police station at Auburn. In 1873 he drew formal plans for a new Parliament House to a sketch by G. S. Kingston. They were not used, but he was appointed to the panel of judges who selected the winning design from the competition which was held subsequently. In the period 1874–1878 while he was with the Engineer-in-Chiefs office, he would have been largely responsible for many of the department's designs, including the Guard House, work on the Treasury Buildings and House of Assembly Chamber,
