The first Secretary of the Treasury in the United States was Alexander Hamilton. Appointed by President George Washington in 1789, Hamilton played a crucial role in establishing the nation’s financial system. He created a central bank, introduced a national currency, and implemented policies that led to the federal assumption of state debts. Hamilton’s vision laid the foundation for modern economic policy in America and advocated for a strong federal government. His influence endures, as he is often credited with shaping the nation’s economic future and fostering capitalist principles.
