John Thomas Macpherson (1872–1921)[1] was a Labour Member of Parliament for the United Kingdom House of Commons constituency of Preston.
A one-time cabin boy, steel smelter and founder of the Steel Smelters' Society[2] he was elected to represent Preston at the United Kingdom general election of 1906. His first recorded question in the House of Commons concerned the wages of armour-plate makers.[3]
At the time of the 1910 Rotherham by-election, Macpherson was an official of the British Steel Smelters, Mill, Iron and Tin-plate Workers’ Union[4] and the union was said to be strong in the Rotherham constituency and willing to pay for his deposit and other expenses to stand in the election.[5]
