It is the only monument in a New York City park which bears the names of living people.The west side of the monument lists Nobel laureates up to 1979, the south side continues the list through 2010, and the east side lists the laureates starting in 2011 (as can be seen in the photos in the gallery of images below, although the website of the New York City Department of Parks incorrectly states that the south side lists the names from 1980 to the present).

S. Eliot, who was a naturalized British subject, nor Albert Einstein, who only became a U.S. citizen years after winning.
