for Jefferson Encylopedia. Click here: The first part of the quotation ("If the American people ever allow private banks to control the issue of their currency, first by inflation, then by deflation, the banks and corporations that will grow up around them will deprive the people of all property until their children wake up homeless on the continent their Fathers conquered") has not been found anywhere in Thomas Jefferson's writings, to Albert Gallatin or otherwise. It is identified in Respectfully Quoted as spurious, and the editor further points out that the words "inflation" and "deflation" did not come into use until 1864 and 1920, respectively.[3]
