Can anyone please help in identifying this font?

Looks like it could be [[http://en.wikipedia.org/wiki/Optima|Optima]] by great [[http://en.wikipedia.org/wiki/Hermann_Zapf|Herman Zapf]] or maybe [[http://new.myfonts.com/fonts/bitstream/zapf-humanist-601/|Zapf Humanist 601]].

I was wondering who designed the font used for the victims' names on the World Trade Center 9/11 memorial
and what is the name of it?
