Italian Americans have founded successful companies, including Bank of America (originally the Bank of Italy), started by Amadeo Giannini, and Chrysler Corporation, founded by Walter Chrysler who was of Italian and German descent.

Italian American architects, such as Pietro Belluschi and artists like Constantino Brumidi (who painted the U.S. Capitol dome), have left their mark on American art and architecture.
