Gurlitt has died: Works from his infamous collection

Artist Wilhelm Lachnit (1899-1962) from Dresden painted this watercolor "Man and Woman in the Window" in 1923. It's one of 25 works from Cornelius Gurlitt's art collection, which were added to the Lost Art online databank in the hope of more quickly determining their origin. Some of the 25 works may have been stolen by the Nazis during World War II.

The watercolor "Couple" by Hans Christoph (1901-1992) was painted in 1924. The Dresden artist was not particularly well known in the 19th century, although he associated with big name artists like Otto Dix, Wilhelm Lachnit and Otto Griebel, who also lived and worked in Dresden at the time.

Christoph Voll (1897-1939) was a recognized German sculptor and designer in the early 20th century - until the Nazis put an end to his career. His works were labeled "degenerate" - not suitable to the Nazis' racist cultural standards. He painted "Monk" in 1921.

Bernhard Kretzschmar (1889-1972) also lived in Dresden, where he worked as a painter and designer. It's unknown exactly when he painted this watercolor, "Streetcar." Many of his works were marked "degenerate" by the Nazis and confiscated. The Allied bombing of Dresden in 1945 was particularly horrific for him: Many of his works were destroyed in the attack.

Painter and designer Otto Griebel (1895-1972) created leaflets and posters for the communist party in Germany and openly protested against the military in his art. The Nazis didn't approve and destroyed many of his works. This undated watercolor, "Child at a Table," survived - and landed in Cornelius Gurlitt's collection.

An undated drawing by Auguste Rodin (1840-1917) is pictured on the left, Otto Dix's 1922 watercolor "The Female Lion Tamer" on the right. Dix (1891-1969) was known for his harsh depictions of reality and was a vocal critic of his time. In 1934, the Nazis banned him from working and exhibiting, adding his work to the "degenerate art" list. Hundreds of his paintings were taken from German museums.

Along with Otto Dix and Otto Griebel, Conrad Felixmüller (1897-1977) belonged to the Dresden Secession, a socially critical artists' group. Felixmüller adopted a realist style and painted this watercolor "Couple in a Landscape" in 1924. His work was also black-listed by the Nazis.

Antonio Canaletto (1697-1768) was an Italian painter known for his detailed cityscapes. To create them, he used what was known as a camera obscura - a predecessor to the modern camera. This print discovered among the Gurlitt collection originated in the late 18th century in Padua.

Eugène Delacroix (1798-1863) painted works that had a huge dramatic impact. He is considered one of the most significant representatives of Romantic painting in France. Epic historical imagery, along with still-lifes and portraits, are included in his oeuvre. Cornelius Gurlitt had an undated pencil sketch in his collection.

Théodore Rousseau (1812-1867) liked to paint outdoors. For the landscape painter, it was essential to capture the minutest details of what he saw. Pictured is an undated sketch of the Seine Valley.
