Gustav Klimt's 1907 oil on canvas, a key work of the Art Nouveau movement, took three years to complete. Commissioned by the wealthy sugar industrialist Ferdinand Bloch-Bauer, it depicts his wife, Adele. Ferdinand, a great admirer of Klimt, commissioned a second portrait of Adele in 1912, making her the only person painted twice by the artist. The artwork's compelling journey is as famous as its artistry. Adele Bloch-Bauer wished it to go to the Austrian State Gallery, but it was seized by German forces in World War II. In 1945, Ferdinand Bloch-Bauer designated ownership to his nephew and nieces, including Maria Altmann. The Austrian government, however, retained it until 2006, when a long court battle finally returned it to the Altmann family. Subsequently, the portrait sold at auction for a then-record $135 million. It is now a cherished highlight at the Neue Art Gallery in New York.
