G. T. Light

[2] 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.

[a] He married Marian Wilson in September 1850 at St Matthew's Church of England, Kensington;[b] they would have six children, of whom four survived infancy.

They supervised erection of German-made prefabricated Palm House in the Botanic Gardens designed by Gustav Runge and opened in 1877.

Light is believed to have designed the south-west section of Government House, the Jervois wing of the State Library of South Australia, the Norwood police station.

[8] Light and Holwell were architects of the Parkside post and telegraph office, an elaborate complex with an attached hall designed to accommodate 500 people.

By November 1849 he had established a workshop and showroom in Pirie Street, "adjacent Wilson's iron store" for manufacturing the euphonicon, and also had a Broadwood piano for hire.

[11] In 1853 he had a shop on Rundle Street east, "nearly opposite the Exeter Hotel", advertising his services as piano and harmonium repairer and tuner,[12] later having such instruments for sale.

[13] Light was in 1854 the first organist employed by St Andrew's Church, Walkerville, presiding at the harmonium at the Walkerville School's annual festival and the debut of the North Adelaide Choral Society[14] and many concerts at which C. J. Kunze (died 1868) played piano, and at the Handel Festival at White's Rooms in 1859, perhaps his last public concert.
