The Knickerbocker Yacht Club was a yacht club in Port Washington, New York.The club was founded in 1874, on the Harlem River at 130th Street in Manhattan, to encourage “Yachting and the cultivation of Naval Science and Seamanship”.In 1907, it moved to Port Washington. It started the Knickerbocker Cup race in 1982, which became internationally recognized.At its peak in the early 1980s, membership consisted of approximately 290 families with 165 boats.World champion runner Lon Myers began his track career running for the club. Bus Mosbacher, who skippered two winning teams in the America's Cup races, and world champion sailor Robert Mosbacher were members of the club.As of 2009, it was the second-oldest yacht club on Long Island Sound.

The American Aeronautical Corporation (AAC) was founded in October 1928 by Enea Bossi, located at 730 Fifth Avenue in Port Washington, New York. Its purpose was to build Savoia-Marchetti seaplanes under license. Licenses were acquired for both the S-55 and the S-56 and both were tested at Miller Army Air Field, but only the latter made it to production.The S-56 was first introduced in Italy two years earlier as a three-seat amphibious aircraft powered by air-cooled radial engines in the 90- to 110 horsepower (82 kW) range. The AAC fitted it with an American Kinner engine. Following on the heels of a boom in the aviation industry in America – largely attributed to Charles Lindbergh’s flight in 1927 – it was among the few foreign designs to be manufactured in the United States under Approved Type Certificates (ATCs) and, at $7,300, was also the first low-priced amphibious aircraft on the U.S. market. The size and price of the vehicle appealed to recreational aviators, despite its difficult handling. On water, the plane lacked a rudder; on ground, the plane only had a non-steerable tail skid (that is: no conventional brakes); and in the air, when the wheels were extended, the added drag complicated the steering.Thirty-six S-56s were built under ATC A-287, which was awarded on 4 January 1930. The S-56 became the first plane used by the New York City Police Department, which used it to enforce flying regulations, assist with sea rescues, and to chase rum-runners during the Prohibition era. A follow-up design, the S-56B, proved even more successful. ATC A-336, for the S-56B design, was awarded on 11 July 1930. The S-56B included a more powerful 125 horsepower (93 kW) Kinner B-5 engine and sold for $7,825. Whereas the prices for the S-56 and S-56B were modest for the time, the Great Depression caused sales to drop significantly by 1933. Two original AAC S-56 planes exist today: one of which is on display at the Cradle of Aviation Museum in Garden City, New York.(photos)In December 1928, the AAC named Captain Hugo (Ugo) Veniero d'Annunzio, son of Gabriele d'Annunzio, as a director and vice president. Captain d'Annunzio had never arrived in the United States in 1917 to supervise the manufacture of Caproni bombing planes at the Fisher Body plant, as an agent of Isotta Fraschini.With a factory already in place in Port Washington, on Long Island, the AAC sponsored the construction of a seaplane base in the town. It was officially dedicated by the striking of a bronze medal on 14 September 1929. The rectangular medal is sized 4 x 2 15/16" (102 x 73mm) and features a one-sided print consisting of a flying boat and an amphibian aloft in the upper-center, a sketch of the projected terminal building at the bottom, a winged male figure at lower left, and at right, the words "Laying of Cornerstone, New York Seaplane Airport September 14th 1929 American Aeronautical Corporation". Prominent speakers at the dedication included Edward P. Warner.In 1933, the American Aeronautical Corporation facility was purchased by Pan Am and became the base for early survey flights for transatlantic air service. In 1937, the first regular commercial transatlantic airline service in America started from the facility. International seaplane flights continued into the early 1940s.

The Polish American Museum is located at 16 Belleview Avenue in Port Washington, New York, USA. It was founded on January 20, 1977. It features displays of folk art, costumes, historical artifacts and paintings, as well as bilingual research library with particular focus on achievements of the people of Polish heritage in America.Nearly everything in the museum, which is housed at the old Port Washington library, was donated by members of the community: from the war memorabilia, army uniforms, Polish medals and weapons, to the books about Poland in both English and Polish. Barbara Szydlowski, president of the museum, remarked that many Polish immigrants made their way to Nassau County about a century ago to work in North Shore estates, but their descendants are dispersed. "We're trying to do more on the history of Poles on Long Island," she said, "but it's very hard because the population is so scattered."The Museum puts a strong emphasis on famous people of Polish ancestry with a portrait of Pope John Paul II displayed prominently along with that of Tadeusz Kościuszko wearing the uniform of Brigadier General of the American Revolutionary Army, and Kazimierz Pułaski as General Commander of the Cavalry under George Washington. There is a room dedicated to Polish Nobel Prize laureates including Marie Curie and Lech Wałęsa. In the music room there are plaster replicas of Frédéric Chopin's death mask and of his left hand, brought in from Warsaw by a museum member. One of the most poignant items on display is the blue-and-white striped jacket of a concentration-camp inmate, a Polish prisoner who was held by the Germans in World War II, donated by a patron who survived as many as seven different camps in 1944–1945, which is now a part of the Holocaust exhibit. One annex of the museum, that has been receiving visitor accolades is the CMS Annex. The CMS (Center for Military Studies Annex) features the military stories of Poles and Polish Americans that took part in the many wars and campaigns that shaped both US and Polish history. Among the featured exhibits is Long Island's own Frank Gabreski the top U.S. ace in the European Theater during WW2. The current director is Gerald Kochan.
