Bronson then pursued a career in purchasing and selling government obligations. He invested in the new American government's debt, assisted by many friends from former officers, including Alexander Hamilton, who had become the first Secretary of the Treasury in Washington's first cabinet. in some cases purchasing it for ten cents on the dollar.
