Harriet Beecher Stowe

She told the story, and the whole world wept
  At wrongs and cruelties it had not known
  But for this fearless woman's voice alone.
  She spoke to consciences that long had slept:
  Her message, Freedom's clear reveille, swept
  From heedless hovel to complacent throne.
  Command and prophecy were in the tone
  And from its sheath the sword of justice leapt.
  Around two peoples swelled a fiery wave,
  But both came forth transfigured from the flame.
  Blest be the hand that dared be strong to save,
  And blest be she who in our weakness came--
  Prophet and priestess! At one stroke she gave
  A race to freedom and herself to fame.
