Stephen Pleasonton

Stephen Pleasonton was the first "Fifth Auditor" of the U.S. Treasury Department; he is historically significant for his part in saving priceless early government documents from possible destruction, but is chiefly remembered today for his singularly bureaucratic work in overseeing the Treasury Department's Lighthouse Establishment during most of its existence. He was also the father of Union Civil War Generals Alfred Pleasonton and Augustus Pleasonton.
