Background
Samuel Osgood was born in Andover, Massachusetts, in 1748. He served as a Continental Army officer during the American Revolutionary War, rising to the rank of colonel, and later served in the Continental Congress and the Massachusetts legislature. President George Washington appointed him the first U.S. Postmaster General in 1789, a position he held until 1791. After retiring from federal service, Osgood became active in New York commercial and civic affairs.
Founding Story
The founding of the modern Citigroup conglomerate is the result of the 1998 merger between Citicorp and Travelers Group, but its foundational corporate DNA traces back to the very dawn of American financial power in the early 19th century. The oldest and most essential pillar of the company is the City Bank of New York, founded in 1812. The founding was orchestrated by Samuel Osgood, the first Postmaster General of the United States. Following the expiration of the charter for the First Bank of the United States (Alexander Hamilton's creation), New York merchants desperately needed a capitalized institution to finance the booming trade occurring through the port of New York. The City Bank stepped into this void, financing the American industrial revolution and heavily funding the Union Army during the Civil War. In 1897, it became the first major US bank to establish a dedicated foreign department, initiating a century-long obsession with global expansion that would eventually define the modern institution. The other crucial foundational pillar was Travelers Group, a financial conglomerate built by Sandy Weill. Weill was one of the most aggressive, hard-nosed corporate consolidators in the history of Wall Street. In 1998, Weill (representing Travelers) and John Reed (the CEO of Citicorp) agreed a stock merger valued at roughly $70 billion that created a combined group worth about $140 billion. Existing law limited affiliations between a commercial bank, an insurer and a securities firm, so the deal closed under a temporary Federal Reserve approval while Weill and Reed lobbied for reform. Congress passed the Gramm-Leach-Bliley Act in 1999, removing those Glass-Steagall limits and allowing Citigroup to keep its combined structure.
