Sir John Smith Teasdale CBE (28 June 1881 – 2 July 1962) was an Australian wheat farmer and administrator.
He worked as a grain merchant before his migration to Western Australia in 1911, where he and a number of his brothers settled to farm in the Bruce Rock area.
Becoming more involved in the farming community, Teasdale was an executive member of the Farmers' and Settlers' Association in 1916 and in 1922 helped found the Wheat Pool of Western Australia, touring Great Britain and the United States to gather information on farming methods.
[1] Teasdale, a Country Party member, successfully lobbied for the 1930 Farmers' Debts Adjustment Act; from 1932 to 1940 he was President of the Primary Producers' Association of Western Australia.
[citation needed] He proposed a twenty per cent reduction in acreage for wheat producing countries in 1932, but opposed the Wheatgrowers' Union of Western Australia when it attempted to withhold wheat supply until a compulsory national pool was established.
