Agitator, educator, organizer. J.B. McLachlan is legendary in Cape Breton as the pre-eminent labour leader of the early twentieth century. Long considered a classic in the field of Canadian social history, this authoritative biography by award-winning scholar David Frank tells the story of McLachlan, champion of Cape Breton’s coal miners and political rabble-rouser who fought tooth-and-nail for social justice across the country. He led the coal miners of Nova Scotia in their struggles for union recognition, defending their cause in the labour wars of the 1920s and uniting them around ideas of industrial democracy and social reconstruction. The battles between mine owners and the miners were epic. Mine owners and their friends in government used violence and intimidation in their efforts to defeat workers. McLachlan was charged with sedition in 1923, and his political trial in Nova Scotia stands as a notorious use of the courts to punish and silence the labour movement and its leaders. By the 1920s and 30s, he was recognized across Canada as a leading spokesman for the radical Left. McLachlan helped change the balance of power in industrial society, advancing the struggle for social and economic justice. Readers today, fighting for better wages, better benefits, better lives, can learn much from McLachlan’s exploits. J.B. McLachlan: A Biography is a rich portrait of a brilliant early twentieth-century Canadian rebel.
