Charles Hope Kerr (1860-1944), a son of abolitionists, was a vegetarian and Unitarian in 1886 when he established Charles H. Kerr & Co. in Chicago. Over the years, his company became a leading publisher of socialist, anarchist, and Wobbly works. Kerr was noted for his translation from the French of the radical workers' anthem, "The Internationale;" his version became the English words sung in the United States (although a different, anonymous English translation is sung in Britain and Ireland). Kerr's version was widely circulated in the Little Red Songbook of the Industrial Workers of the World.
