Thomas in 1910 as Thomas Brothers Company in Hammondsport, New York, the company moved to Hornell, New York and later Bath, New York, New York, the same year, remaining in Bath until 1915, During 1912 and 1913, the company operated the affiliated Thomas School of Aviation at Cayuga Lake in New York state (taking a page from Glenn Curtiss, who did much the same).

In 1915, Thomas Brothers built T-2 tractor biplanes (designed by Benjamin D. Thomas, no relation to the brothers and also an Englishman, formerly of Vickers, Sopwith, and Curtiss, and later the company's chief designer) for the Royal Naval Air Service. and (fitted with floats in place of wheels) to the United States Navy as the SH-4. In 1916, the company won a contract from the United States Army Signal Corps for two aircraft for evaluation, the D-5.

In January 1917, the company merged with the Morse-Chain Company and was renamed the Thomas-Morse Aircraft Corporation. The company then made an attempt at selling training biplanes to the United States Army and was successful with the S-4 trainer (which included a handful of S-5 floatplanes and a single S-4E) and MB series of fighters. The last company design was the O-19 observation biplane. It became the Thomas-Morse Division of Consolidated Aircraft Corporation in 1929, and ceased business in 1934.
