John Calvin Coolidge, Jr. (4 July 1872–5 January 1933) was the 30th President of the United States (1923–1929).
Economist and historian Robert Murphy describes Coolidge as follows:
"As far as fiscal responsibility, Coolidge was superlative.
"In contrast to the onerous burden created under Woodrow Wilson, during the Coolidge years the bottom bracket's tax rate was brought down to 1.5 percent by 1926, while an upper-middle-class (though hardly "filthy rich") household earning $20,000 saw its tax rate slashed to 9 percent.
"He ran budget surpluses every year he was in office."
