Frederic John Napier Thesiger, 1st Viscount Chelmsford,, styled the Lord Chelmsford until 1921, was a British statesman. He served as Governor of Queensland from 1905 to 1909, Governor of New South Wales from 1909 to 1913, and Viceroy of India from 1916 to 1921, where he was responsible for the creation of the Montagu–Chelmsford Reforms. After serving a short time as First Lord of the Admiralty in the government of Ramsay MacDonald, he was appointed the Agent-General for New South Wales by the government of Jack Lang before his retirement.

The Government House is the heritage-listed vice-regal residence of the governor of New South Wales, Australia, located on Conservatorium Road in the Sydney central business district adjacent to the Royal Botanic Garden, overlooking Sydney Harbour, just south of the Sydney Opera House. Constructed between 1837 and 1843, the property has been the vice-regal residence of the Governor since Sir George Gipps, except for two brief periods; the first between 1901 and 1914, when the property was leased to the Commonwealth of Australia as the residence of the Governor-General of Australia, and the second from 1996 to 2011.
