William Wilgus, New York Central Railroad's largely self-taught chief engineer, was the mastermind behind Grand Central Terminal's innovative engineering technology. With the plan for electrification and the sinking of the railroad tracks below grade, while building the new modern terminal, Wilgus also convinced railroad officials to commercialize the air above the new street-level decking. In leasing the area above the tracks to developers, the Railroad could increase its profits and create a bustling business district that surrounded, supported, and benefited from Grand Central Terminal. Terminal City, as it was called, began to develop even before GCT was complete in 1913. Between 1909 when the Grand Central Post Office opened and the early 1930s when the Depression largely halted construction, the neighborhood boomed with hotels, apartment hotels, private clubs, and office buildings. Many of these structures were designed by Warren & Wetmore, one of the two architectural firms that created Grand Central. Most of the best-known hotels of Terminal City, including the Biltmore, Roosevelt, and the Commodore, were constructed by the mid 1910s, while the office buildings, including the Graybar and New York Central Buildings, were largely completed in the 1920s. This walk does not propose to be a complete list of all Terminal City development. It does not include any post-World War II constructions and it concerns itself ONLY with some of the Terminal City structures that are still extant. Some of the buildings will be easily recognizable, while others, though technically the same structure, bear no resemblance to their former selves. So lace up some comfortable shoes and let's get exploring.

Grand Central Post Office, ca. 1910. Constructed by the associated architecture firms of Reed & Stem and Warren & Wetmore, the Grand Central Post Office was completed in 1909, three years before Grand Central Terminal (by the same architects) was finished. It is the oldest surviving structure of the area that became Terminal City. When opened the entire structure was devoted to postal functions. At seven stories, the post office is considerably shorter than most of the Terminal City structures (excepting GCT, itself). In 1992, though, a 31-story tower was built within and on top of the 1909 building.

Beloved Academy Award winning German-Jewish actor Luise Rainer, arrived in America in 1935, as fascism continued to seduce Europe. In December 1940, a mere five years after arriving, having already won 2 Oscars two years in a row, and with America still sitting it out, and the war in Europe headlining the news, Rainer guest starred at The Forward's radio station WEVD, "Salute To America" program highlighting American democracy.
