Alfred Vellucci
An Italian American, Vellucci was opposed to the idea that Leif Ericcson, rather than Christopher Columbus, discovered America. After a group of scholars from Harvard promoted the claim that Ericcson discovered America, he proposed a motion to the Cambridge City Council that officially renamed Harvard Square to Columbus Square. He also planted a large tree in front of the Harvard Lampoon Building, claiming that it was an eyesore and arguing that the "Harvard Lampoon" had insulted Italian Americans by claiming that the Irish discovered America. He feuded with the "Harvard Lampoon" for years. The paper often satirized him, one issue running an Alfred E. Neuman style picture of him on its cover. On one occasion, he unsuccessfully proposed a city ordinance declaring their headquarters a public urinal.
Earth-Three
Earth-Three was introduced by Gardner Fox and Mike Sekowsky in a 1964 issue of "Justice League of America". Earth-Three's history is depicted as a mirror image to that of the Earth we know. On Earth-Three, Christopher Columbus was American and discovered Europe; England (a colony of America) won freedom in a reversed form of the Revolutionary War (with George Washington surrendering his sword to Charles Cornwallis) in 1774; President John Wilkes Booth was assassinated by actor Abraham Lincoln. Crucially, Earth-Three was home to an analogue to the Justice League, the Crime Syndicate of America.
