Igor I. Sikorsky, engineering manager of the Vought – Sikorsky Division of the former United Aircraft Corporation, used the Stratford, Conn., sites to design, build, and test his innovative helicopter designs. Sikorsky’s VS-300 model helicopter was the world’s first design which used the now industry-standard single main rotor with an auxiliary anti-torque tail rotor.

Pearson Field, named for U.S. Army Lt. Alexander Pearson Jr., a prominent early aviator who died in an airplane crash in 1925, is the oldest continuously operating airfield in the Pacific Northwest, and one of the oldest in the United States. In 1905, the field, then known as the Fort Vancouver Polo Grounds, was the landing site for a dirigible launched from the Lewis and Clark Centennial Exhibition in Portland, Ore. This marked the first crossing of the Columbia River by air, and the first time an airship was used to deliver a letter.

Bell Aircraft, founded in 1935 by Lawrence Dale “Larry” Bell, based its primary manufacturing facility in Wheatfield, New York, where several important aircraft were designed and produced. During the World War II era, the plant produced the P-39 Airacobra and the P-63 Kingcobra fighters. The P-39 was used to great effect by the Soviet Air Force, with the highest number of individual kills recorded by any U.S.-produced fighter aircraft during the war. The plant also designed and manufactured the P-59A Airacomet, the first U.S.

On December 18, 1928, Arthur Rawson, a factory pilot for the Cierva Autogiro Company, and then Harold F. Pitcairn, flew a Cierva C.8W Autogiro from Building #3 at Pitcairn Field #2. The flights marked the first time a rotary-wing aircraft was successfully flown in the U.S.

 On 19 August, the AIAA Historic Aerospace Sites Committee dedicated Kitty Hawk, NC, as a historic aerospace site, following a decades-long negotiation with the U.S Park Service. A historic marker was unveiled at a 0930 hrs ceremony as part of the First Flight Society’s National Aviation Day at Kitty Hawk. At this site on 17 December 1903, Orville and Wilbur Wright achieved the first sustained, controlled heavier-than-air flight of an aircraft, opening a new era of transportation throughout the world.

The federal government’s first physical science research laboratory was chartered by Congress on March 3, 1901, as the National Bureau of Standards, which became the National Institute of Standards and Technology in 1988. Recognizing the critical importance of chemical measures and standards, NIST established the Chemistry Division as one of its first programs.

Prior to its merger with the Carnegie Institute of Technology in 1967 to form Carnegie Mellon University, the nonprofit Mellon Institute for Industrial Research was a major, independent research corporation dedicated to promoting applied research for industry and educating scientific researchers for the benefit of society as a whole. The Institute educated hundreds of fellows for careers in industrial research and helped to sell the very idea of research to manufacturers.

Rachel Carson’s Silent Spring, published in 1962, was a landmark in the development of the modern environmental movement. Carson’s scientific perspective and rigor created a work of substantial depth and credibility that sparked widespread debate within the scientific community and the broader public about the effect of pesticides on the natural world. These discussions led to new policies that protect our air, our water, and, ultimately, our health and safety.

The American Chemical Society, the world’s largest scientific society, celebrated its 125th anniversary in 2001. Founded in 1876 in New York City, the Society now has 186 local sections in all 50 states, international chapters, and 32 technical divisions that bring together scientists with interests ranging from small business to environmental protection.

The text of the plaque commemorating the landmark reads:

Izaak Maurits Kolthoff (1894–1993) has been described as the father of modern analytical chemistry for his research and teaching that transformed the ways by which scientists separate, identify, and quantify chemical substances. Once a collection of empirical recipes and prescriptions, the field of analytical chemistry is today an essential branch of chemistry built upon solid theoretical principles and experimental techniques, the basis of which was formed over the course of Kolthoff’s nearly 80-year career.
