GALVESTON, Texas—Galveston is honoring boxing legend Jack Johnson with a historical marker in observance of his first world heavyweight title by an African American fighter.

The Houston Chronicle reports ( http://bit.ly/MJXMCR) the Galveston-born fighter's family believes the marker unveiled Saturday helps make amends for his 1912 indictment under a federal law historians believe aimed to punish him for marrying outside his race. It made it illegal for a man to take a woman across state lines for immoral purposes.

Presidents George W. Bush and Barack Obama have not responded to congressional resolutions and petitions for a pardon for Johnson.

He became the "Colored World Heavyweight Champion" in 1903 before taking the overall title from Tommy Burns in 1908 in an Australian bout.
