Andrew Mellon

On March 24, 1855, in Pittsburgh, Pennsylvania, Andrew Mellon was born into a family whose banking and industrial ventures defined the city's rising capitalist elite. He studied briefly at the Western University of Pennsylvania before leaving to work in T. Mellon & Sons, where he learned finance, investment, and corporate management. Those early experiences made him one of the most powerful bankers in the industrial Northeast long before he entered cabinet government.

Mellon became secretary of the treasury in 1921 under Warren G. Harding and remained in office through the administrations of Calvin Coolidge and Herbert Hoover. He pushed major tax cuts, debt reduction, and a pro-business fiscal program that shaped federal policy during the 1920s and into the opening years of the Great Depression. After leaving Treasury in 1932, he served as ambassador to Britain and later helped establish the National Gallery of Art in Washington.

Mellon's tax policies and fiscal conservatism remained central to debates over supply-side economics, progressive taxation, and the state's role in stabilizing markets. His art philanthropy also left a permanent institutional mark through the National Gallery of Art, one of the major cultural legacies of interwar wealth.
