Object statement
Kerosene testing thermometer in case, glass / mercury / wood, made by Flavelle Brothers, Australia, 1885-1900, used by Sydney Observatory, New South Wales, Australia, 1885-1920
This thermometer was used at Sydney Observatory to test the temperature of stored kerosene. Kerosene was used as a fuel source for lamps and lanterns.

The thermometer was made by Flavelle Brothers & Co., who were significant Australian scientific instrument makers in the 19th century.

This thermometer remains of national significance due to its pioneering role in Australian science and its association with Australia's earliest astronomers. It is also of international significance due to its association with nineteenth century scientific instruments and their makers.

Written by Erika Dicker

This thermometer was made between 1885 and 1920 in Sydney, New South Wales, Australia.

John Flavelle arrived in Australia around 1842 and worked for Australia's first professional photographer, G. B. Goodman. Four years later he established an optician's and watchmaker's business in Sydney with Samuel Brush which was a highly successful business and had premises at 488 George St and also 478 George St. The partnership dissolved in 1849, and John Flavelle continued to run the 478 George St property, whilst Brush worked from 488 George St. Brush went on to work with Flavelle's brother in law, William McDonnell. John Flavelle was joined by his brother Henry. Both these separate business grew successfully and they were significant retailers of scientific instruments in Sydney in the late 1800s.

It is recorded that Henry Flavelle sailed to Australia with his wife and child on the vessel The Chartley Castle leaving Europe in February and arriving in Sydney mid June, 1849. He was travelling with 16 packages of merchandise, including new and innovative scientific instruments, to stock his brother's new shop

The business operated under the name Flavelle Brothers until 1850, then Flavelle Brothers and Co until 1869.
