This chapter analyzes the story of a transnational figure who hardly ever crossed a national border in his career as labor leader. Terence Powderly (1849-1924) was born in Carbondale, Pennsylvania, in 1849, to Irish immigrants. He entered the labor force as a switchman for the Delaware and Hudson railroad at the age of 13, as the Civil War raged across the United States, and became a machinists’ apprentice at the age of 17. He was marked out very early as a rising star in the American labor movement, rising quickly in the Machinist and Blacksmith’s Union after joining it in 1871. In 1874, a year after the Panic of ’73 brought economic depression to the United States and forced Powderly west to find work, he joined a relatively new, secret union that he would be associated with for the rest of his life: The Noble and Holy Order of the Knights of Labor.
