The entry

Georges Urbain split ytterbium in 1907 and named the new element after Lutetia, the Roman settlement on the Seine that became Paris. Carl Auer von Welsbach reached the same result independently and proposed cassiopeium, which German publications used into the 1950s. Charles James in New Hampshire had also isolated it, but did not press his claim.
