Milton Elting Hebald (May 24, 1917 – January 5, 2015) was a sculptor who specialized in figurative bronze works.
 Twenty-three of his works are displayed in public in New York City, including the statues of Romeo and Juliet and The Tempest in front of the Delacorte Theatre in Central Park.
 His major work is a 220 ft , 12-piece "Zodiac Screen", then the largest sculpture in the world, commissioned by Pan-American Airlines for its terminal at John F. Kennedy International Airport, and now owned and stored by the Port Authority of New York and New Jersey.
The construction of New York City's first World Trade Center complex was conceived as an urban renewal project, spearheaded by David Rockefeller, to help revitalize Lower Manhattan.
 The project was developed by the Port Authority of New York and New Jersey, which hired architect Minoru Yamasaki who came up with the specific idea for twin towers.
 After extensive negotiations, the New Jersey and New York state governments, which oversee the Port Authority, agreed to support the World Trade Center project, which was built at the site of Radio Row in the Lower West Side of Manhattan, New York City.
 To make the agreement acceptable to New Jersey, the Port Authority agreed to take over the bankrupt Hudson & Manhattan Railroad, which brought commuters from New Jersey to the Lower Manhattan site and, upon the Port Authority's takeover of the railroad, was renamed PATH.
