Prosper de Mestre

Prosper de Mestre (1789–1844) was a prominent businessman in Sydney from 1818 until near his death in 1844. He was French born, but also a "citizen of the world", who played an important role in the development of commerce and banking in the English Colony of New South Wales. He became a successful merchant and business leader in Sydney. In 1825 he became the second person to be naturalised in the Colony. In addition to being one of the early directors of the Bank of New South Wales (for periods between 1826 and 1842), he was also a founder of the local insurance industry, a member of the committee of the Agricultural Society of New South Wales, and became involved in importing, shipping and whaling. There are numerous references to his business activities in the Colonial Secretary's Papers of the day.

De Mestre was also the father of Etienne Livingstone de Mestre (1832–1916), the trainer of Archer the horse who won the first and second Melbourne Cups in 1861 and 1862, and the foremost Australian horse trainer of his era. His other descendants include: Sarah Melanie de Mestre (1877–1961) who distinguished herself as a nurse in France and Flanders in World War I, and whose decorations included the Royal Red Cross which was presented to her at Buckingham Palace by King George V on 3 June 1918 (the King's birthday); Roy de Maistre (1894–1968), a successful Australian artist; Guboo Ted Thomas (1909–2002) a prominent Aboriginal leader, and the last initiated tribal elder on the South Coast of New South Wales; Margaret Augusta de Mestre (1915–1942), a nurse who was killed in action on a hospital ship on 26 February 1942 in the bombing of Darwin during World War II; Neville de Mestre (c.1938- ), an eminent Australian mathematician and author, Emeritus Professor of Maths at Bond University, and who has held the titles of World Iron Man champion in the 60-64 age group, and Australian and World Masters surfing champion in the over-65 group for body surfing; and Lloyd Nolan Hornsby (1947- ), a prominent Aboriginal artist.
