Stanley Yale Beach (1877 – 1955) was a wealthy aviation pioneer, who was an early financier of Gustave Whitehead, who claimed to have made powered controlled flight before the Wright brothers.

Beach attended Yale Sheffield Scientific School like his father, and afterward developed a lifetime interest in aeronautics, engineering, and inventing.

[19] He later created the Scientific Aeroplane Company of Stratford, a Connecticut airplane manufacturer that proposed to build machines for fairs and other amusement enterprises.

[21][better source needed] Around that time, with his Scientific Aeroplane Company of New York, he negotiated with the British government to sell them nine huge triplanes capable of crossing the Atlantic Ocean in one flight, which was regarded with skepticism by aviation experts.

When Andrew Carnegie created his new Endowment for International Peace in 1910, Stanley Yale Beach suggested using a portion of the capital to develop wireless power airships to end and prevent future wars.

[3] His personal correspondences for business interests are part of the Beinecke Rare Book & Manuscript Library at Yale University.

Correspondents included Charles Nungesser and François Coli, the aviators who tried the first non-stop transatlantic flight from Paris to New York.

[27] He was also a Freemason of the American Legion, and served in the Ambulance Company, Field Hospital, during World War I Beach died July 13, 1955, at the age of 78 in New York.

His father Frederick C. Beach had given him a trust fund of $500,000 in 1914; about 350 million dollars in 2024 money in relation to GDP,[28] and was the owner and secretary-treasurer of Scientific American at the time.
