. Cities Services, a petroleum company, built the tower to house its corporate headquarters as well as rental floors. The company’s founder and chairman, Henry L. Doherty, an eccentric engineer and inventor supervised the design of the tower and intended to live in the penthouse, although poor health prevented him from ever doing so. (The penthouse never came into existence, but the top story was once an observatory open to the public. It was originally furnished with chairs and other articles of furniture designed by Le Corbusier and Marcel Breuer.) The skyscraper was originally known as 60 Wall Street, a more prestigious address that was justified by the tower’s connection by a footbridge (and an underground walkway) to a building with that address, now demolished. The 67 story tower rises as a slender shaft that is articulated with a series of shallow receding planes and at the top steps back to crest a glass observatory which is illuminated at night. The brick cladding lightens from a browny-beige to a creamy-tan as the tower ascends. The base of the building is clad in a luxurious polished pink and black Minnesota granite. The American International Building was the last high-rise to go up before the Depression hit, and consequently, the last to be erected before WWII. Post-war, the only buildings that ever surpassed it in height, were the World Trade Center’s twin towers. This is currently Lower Manhattan’s tallest building. The skyscraper is currently undergoing a residential conversion. #70pine #architecture #artdeco #skyscraper #wallstreet #downtownnyc (at 70 Pine Street)
