CENSORSHIP
A native of Galveston, Texas, Jack Johnson (1878–1946) was the first black heavyweight boxing champion, from 1908 to 1914. His stunning victory over white champion Jim Jeffries (who had earlier refused to fight black boxers) in 1910 resulted in race riots across the country and led to a ban on the interstate transportation of boxing films. A 2005 Ken Burns documentary, Unforgivable Blackness, chronicles Johnson’s life. © Bettmann/Corbis
