In 1903, the firm Ernst & Ernst was founded in Cleveland, Ohio, by Alwin C. Ernst, and his brother, Theodore Ernst. In 1906, Arthur Young & Co. was set up by a Scotsman accountant, Arthur Young, in Chicago. Starting in 1924, these two American firms became allied with prominent British firms; Young with Broads Paterson & Co.; and Ernst with the aforementioned Whinney Smith & Whinney. The latter of these two mergers spawned Anglo-American partnership Ernst & Whinney in 1979.
A decade later, in 1989, Ernst & Whinney merged with the fifth largest firm globally at the time, Arthur Young & Co., to create Ernst & Young
