For its first eight decades, the firm operated independently and merged with several Wall Street securities firms including Hayden Stone & Co. and Loeb Rhoades & Co.. In 1981, Shearson was acquired by American Express and operated as a subsidiary of the financial services company before being merged with Lehman Brothers Kuhn Loeb in 1984 and E.F.

The Shearson name was discontinued in 1994.

Hutton, Hayden Stone & Co., Shearson, Hammill & Co., Loeb, Rhoades & Co., Hornblower & Company and Cogan, Berlind, Weill & Levitt, which ultimately came together under the ownership of American Express. The Shearson name traces its origins to the formation of "Shearson, Hammill & Co.", a Wall Street brokerage and investment banking firm founded in 1902 by Edward Shearson and Caleb Wild Hammill. The firm originally built its business as a stock broker as well as a broker of various commodities, particularly grain and cotton. The firm was a member of the New York Stock Exchange, the Chicago Stock Exchange and the Chicago Mercantile Exchange. Before forming the firm, Shearson had served as comptroller of U.S. Steel and of Federal Steel Company before that. Shearson, who was raised in Ontario, Canada began his career as an auditor for the Wisconsin Central Railroad before taking a position in the steel industry in 1898. Shearson was an active member of New York society. Hammill, who was raised in Albion, Michigan, moved first to Chicago and subsequently to New York in 1890. The firm was originally headquartered in the Empire Building at 71 Broadway in New York City and maintained another main office in Chicago.
