Alexander Porfiryevich Borodin (12 November 1833 – 27 February 1887) was a Russian Romantic composer and chemist of Georgian–Russian parentage. He was a member of the group of composers called The Five (or "The Mighty Handful"), who were dedicated to producing a specifically Russian kind of art music. He is best known for his symphonies, his two string quartets, and his opera Prince Igor. Music from Prince Igor and his string quartets was later adapted for the musical Kismet.
