Albert Einstein Memorial adjacent to the National Academy of Sciences.
From Wikipedia:
"The statue was sculpted by Robert Berks in 19 sections and then welded together. It weighs 7,000 pounds (3.2 metric tons) and would stand 21 feet (6.4 m) high. The statue sits on a bench that is white granite from Mount Airy, North Carolina."
From NAS web site:
"The star map at the statue's base--a 28-foot field of emerald pearl granite from Larvik, Norway, is embedded with more than 2,700 metal studs representing the planets, sun, moon, stars, and other celestial objects accurately positioned by astronomers from the U.S. Naval Observatory as they were on the dedication date."
