"Every year, the names of the American Nobel Laureates from the previous year are inscribed onto the monument and unveiled at an annual ceremony."
The event will be in Theodore Roosevelt Park, adjacent to the American Museum of Natural History. The invitation letter says "This is the location of the Nobel Monument, raised in 2003 to honor Alfred Nobel and all American recipients of the Nobel Prize, who along with you now number 332."
I was in NYC on 5/17/2014 and took a walk with Itai Ashlagi and Jacob Leshno to see the monument.
(There aren't so many opportunities to see your name in stone:)
