Joel Emmanuel Hägglund was born in October 7, 1879 in Gävle, Gästrikland (X), Sweden.
He emigrated to North America in 1902. He learned English while working various jobs across the United States. During that time as an immigrant worker, he found himself frequently un- or underemployed, and started writing songs and drawing cartoons to support labor unions.
Joe is best remembered for his work as a labor activist and songwriter. He was also a member of the Industrial Workers of the World (IWW or "Wobblies"). Joe's most famous songs include The Preacher and the Slave, The Tramp, There is Power in a Union, The Rebel Girl, and Casey Jones--The Union Scab. The Preacher and the Slave was first sung in public by Harry K. McClintock, hobo serenader extraordinaire.
Joe used the alias Joseph Hillström.
Joe was accused of murder, and though he was most likely innocent, he was convicted and found guilty. Just prior to his execution, Joe had written to Bill Haywood, an IWW leader, saying, "Goodbye Bill. I die like a true blue rebel. Don't waste any time in mourning. Organize ... Could you arrange to have my body hauled to the state line to be buried? I don't want to be found dead in Utah."
Joe died November 19, 1915, executed by firing squad. He was cremated and his ashes distributed to members of the International Workers of the World (Wobblies).
