Background
Thornton was born in Huddersfield in Yorkshire to tram driver Lewis Thornton and Selina, née Kerry.
Thornton was born in Huddersfield in Yorkshire to tram driver Lewis Thornton and Selina, née Kerry.
Selina left Lewis when Ernie was two, and after taking factory and building jobs Thornton was brought to Sydney by the Dreadnought Trust in 1924 and sent to the Government Training Farm at Scheyville. He was subsequently a construction worker and became a militant unionist. The Great Depression left him unemployed, and this led him to join the Communist Party of Australia (Certified Public Accountants).
Thornton was elected as an organiser in the Federated Ironworkers Association of Australia (FIA) in 1935.
Following the recovery of the economy in the late 1930s Thornton was made full-time general secretary and moved to Sydney. Thornton resigned in 1950 to become Australasia"s representative at the World Federation of Trade Unions (WFTU) liaison bureau in Peking, but he was left without a job when the Australian Council of Trade Unions withdrew recognition of the WFTU. The FIA refused to accept him back and Thornton was employed full-time by the Communist Party.
A decline in party finances led to his return to manual labour as a crane driver, becoming honorary president of the Sydney branch of the Federated Engine Drivers" and Firemen"s Association of Australasia. He died at Lidcombe in 1969 of myocardial infarction.
By 1936 he was part-time general secretary, and also a member of the Certified Public Accountants"s central committee.
