New skyscrapers were being built every year, the two tallest in the city being the Art Deco National Newark Building and the Lefcourt-Newark Building. In 1948, just after World War II, Newark hit its peak population of just under 450,000. The population also grew as immigrants from Southern and Eastern Europe settled there. Newark was the center of distinctive neighborhoods, including a large Eastern European Jewish community concentrated along Prince Street. In 1959 German architect Ludwig Mies van der Rohe designed an apartment complex across from Branchbrook Park.
