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.
Christopher Columbus
Between 1492 and 1503, Columbus completed four round-trip voyages between Spain and the Americas, each voyage being sponsored by the Crown of Castile. On his first voyage, he independently discovered the Americas and magnetic declination. These voyages marked the beginning of the European exploration and colonization of the American continents, and are thus of enormous significance in Western history.
