History of the US Dollar
The US dollar was established by the Coinage Act of 1792, following the Constitution's 1789 grant of currency-issuing power to Congress. It replaced the patchwork of colonial and foreign currencies (including Spanish silver dollars) that had circulated in the early United States.
The dollar left the gold standard domestically in 1933 and internationally in 1971 (the end of the Bretton Woods system), after which its value against other currencies has floated on foreign exchange markets rather than being fixed to a metal or another currency.
Historical origin. US Dollar was not the invention of a single named person; it developed through the process described above.
