16 September 1910 to 7 October 1911 and 27 July 1916 to 28 June 1917
Frank Wilson was born in England. He spent some time going to school in Germany and was later indentured to a firm of shipbrokers and timber merchants. In 1887, he sailed to Queensland to take up a job as manager of a company that was a railway contractor, flour miller and machinery merchant.
Four years later he relocated to Perth to manage a timber company in Canning. He was elected to the Legislative Assembly in 1897 as "a direct opponent of the Forrest Government". Two years later his seat was abolished forcing him to contest the seat of Perth which he won in 1901. However, he was defeated at a poll that same year after his appointment as Minister for Mines in the Morgans government.
In 1904, he stood again for Parliament and was successful, holding the seat of Sussex until 1917.
Wilson was appointed Minister for Works in the Rason government in 1905, then Treasurer, Minister for Education and Minister for Agriculture in the Moore Government in 1906. He became Minister for Works in 1909. A year later, he was appointed Premier and Colonial Treasurer after the resignation of Sir Newton Moore, only to be defeated at the polls the following year.
Under Wilson, the government of the day introduced legislation that saw the establishment of the University of Western Australia. In June 1911, with Parliament's approval Wilson and his wife represented the State at the coronation of King George V and Queen Mary.
He held the job as Opposition leader until 1916, when he was again appointed Premier and Treasurer on the defeat of Premier John Scaddan. But 11 months later he resigned office and sat as an independent after H.B. Lefroy was asked to lead the National Party (coalition) Government. Three months later there was a general election and he lost the seat of Sussex - but only by a margin of four votes.
The following year, aged 59, he died at Claremont and was buried at Karrakatta Cemetery.
