Lord Byron

Vincent Van Gogh, 1889

She walks in beauty—like the night
  Of cloudless climes and starry skies,
And all that's best of dark and bright
  Meet in her aspect and her eyes;
Thus mellowed to the tender light
  Which heaven to gaudy day denies.

George Gordon Byron, commonly known simply as Lord Byron, British poet (1788 – 19 April 1824)

Lord Byron is regarded as one of the greatest British poets and remains widely read and influential, both in the English-speaking world and beyond. Byron served as a regional leader of Italy's revolutionary organisation, the Carbonari, in its struggle against Austria. He later travelled to fight against the Ottoman Empire in the Greek War of Independence, for which Greeks revere him as a national hero - there is even a municipality in Greater Athens that bears his name (Vyronas). Lord Byron died on 19 April 1824 from a fever contracted while in Missolonghi, Greece.
