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.
Alexander von Humboldt
Leaving from Cuba, Humboldt decided to take an unplanned short visit to the United States. Knowing that the current U.S. president, Thomas Jefferson, was himself a scientist, Humboldt wrote to him saying that he would be in the United States. Jefferson warmly replied, inviting him to visit the White House in the nation's new capital. In his letter Humboldt had gained Jefferson's interest by mentioning that he had discovered mammoth teeth near the Equator. Jefferson had previously written that he believed mammoths had never lived so far south. Humboldt had also hinted at his knowledge of New Spain.
