Kahn drew up the design in 1973, rendering it with soft charcoal on yellow tracing paper. He had readied it for construction in 1974, but New York Governor Nelson Rockefeller, a prime mover of the project, became vice president to Gerald Ford and got distracted by mightier demands...
Then Kahn died of a heart attack in a public bathroom in New York’s Pennsylvania Station at age 73.

Though I haven't seen it yet, this is looking like an absolutely stunning memorial (not just because it is Kahn). The site overlooking the river, the landscaping, and the Ando-esque (or rightfully Kahnesque) etherial proportions look really good.
