Which Russian artist painted "Portrait of an Unknown Woman"?

Portrait of an Unknown Woman, also known as The Unknown Woman, An Unknown Lady or Stranger (Russian: Неизвестная, tr. Neizvestnaya) is an oil painting by the Russian artist Ivan Kramskoi, painted in 1883. The model, whose identity is unknown, is a woman of "quiet strength and forthright gaze". It is one of Russia's best-known art works, although a number of critics were indignant when the painting was first exhibited and condemned what they saw as a depiction of a haughty and immoral woman. Its popularity has grown with changes in public taste.

The painting hangs in the Tretyakov Gallery, Moscow, while an earlier version, also dated 1883, is housed at the Kunsthalle Kiel.

Ivan Nikolaevich Kramskoi (June 8 (O.S. May 27), 1837, Ostrogozhsk – April 6 (O.S. March 24), 1887, Saint Petersburg; Russian: Ива́н Никола́евич Крамско́й) was a Russian painter and art critic. He was an intellectual leader of the Russian democratic art movement in 1860-1880.
