"Big Bill" Haywood born in Salt Lake City, Utah: Leader of Western Federation of Miners, Wobblies (IWW) founder - 1869
And this:

February 4, 1869 - Labor leader and Industrial Workers of the World co-founder William D. "Big Bill" Haywood was born. A hard-rock miner at the age of nine, Haywood became secretary-treasurer of the Western Federation of Miners in 1900 and in 1905 co-founded the IWW. In 1907 he was charged in the bombing murder of former Idaho Governor Frank Steunenberg but was acquitted. His defense attorney was Clarence Darrow. He helped lead textile strikes in Lawrence, Massachusetts, in 1912 and Paterson, New Jersey, in 1913, but his radicalism increasingly estranged him from many in the labor movement, including his old union, which dismissed him in 1918. That same year he was convicted of violating alien and sedition acts in effect during World War I and was sentenced to 20 years in prison. He jumped bail and fled to the Soviet Union, where he died in 1928. He is buried beneath the Kremlin walls.
