Egon Schiele (June 12, 1890 – October 31, 1918) was an Austrian painter. A protégé of Gustav Klimt, Schiele was a major figurative painter of the early 20th century. His work is noted for its intensity, and the many self-portraits the artist produced. The twisted body shapes and the expressive line that characterize Schiele's paintings and drawings mark the artist as an early exponent of Expressionism.

When Schiele was 15 years old, his father died from syphilis, and he became a ward of his maternal uncle, Leopold Czihaczec, a railway official. Although he wanted Schiele to follow in his footsteps, and was distressed at his lack of interest in academia, he recognised Schiele's talent for drawing and unenthusiastically allowed him a tutor; the artist Ludwig Karl Strauch. In 1906 Schiele applied at the Kunstgewerbeschule (School of Arts and Crafts) in Vienna, where Gustav Klimt had once studied. Within his first year there, Schiele was sent, at the insistence of several faculty members, to the more traditional Akademie der Bildenden Künste in Vienna in 1906. His main teacher at the academy was Christian Griepenkerl, a painter who's strict doctrine and ultra-conservative style frustrated and dissatisfied Schiele and his fellow students so much that he left three years later.

In 1907, Schiele sought out Gustav Klimt. Klimt generously mentored younger artists, and he took a particular interest in the gifted young Schiele, buying his drawings, offering to exchange them for some of his own, arranging models for him and introducing him to potential patrons. He also introduced Schiele to the Wiener Werkstätte, the arts and crafts workshop connected with the Secession. In 1908 Schiele had his first exhibition, in Klosterneuburg. Schiele left the Academy in 1909, after completing his third year, and founded the Neukunstgruppe ("New Art Group") with other dissatisfied students.

Klimt invited Schiele to exhibit some of his work at the 1909 Vienna Kunstschau, where he encountered the work of Edvard Munch, Jan Toorop, and Vincent van Gogh among others. Once free of the constraints of the Academy's conventions, Schiele began to explore not only the human form, but also human sexuality. At the time, many found the explicitness of his works disturbing.

In 1911, Schiele met the seventeen-year-old Valerie (Wally) Neuzil, who lived with him in Vienna and served as a model for some of his most striking paintings. Very little is known of her, except that she had previously modelled for Gustav Klimt and might have been one of his mistresses. Schiele and Wally wanted to escape what they perceived as the claustrophobic Viennese milieu, and went to the small town of Český Krumlov (Krumau) in southern Bohemia. Despite Schiele's family connections in Krumau, he and his lover were driven out of the town by the residents, who strongly disapproved of their lifestyle, including his alleged employment of the town's teenage girls as models.

Together they moved to Neulengbach, 35 km west of Vienna, seeking inspirational surroundings and an inexpensive studio in which to work. As it was in the capital, Schiele's studio became a gathering place for Neulengbach's delinquent children. Schiele's way of life aroused much animosity among the town's inhabitants, and in April 1912 he was arrested for seducing a young girl below the age of consent.

In 1914, Schiele glimpsed the sisters Edith and Adéle Harms, who lived with their parents across the street from his studio in the Viennese suburb of Hietzing, 101 Hietzinger Hauptstrasse. They were a middle-class family and Protestant by faith; their father was a master locksmith. In 1915, Schiele chose to marry the more socially acceptable Edith, but had apparently expected to maintain a relationship with Wally. However, when he explained the situation to Wally, she left him immediately and never saw him again. This abandonment led him to paint Death and the Maiden, where Wally's portrait is based on a previous pairing, but Schiele's is newly struck. (In February 1915, Schiele wrote a note to his friend Arthur Roessler stating: "I intend to get married, advantageously. Not to Wally.") Despite some opposition from the Harms family, Schiele and Edith were married on 17 June 1915, the anniversary of the wedding of Schiele's parents.

Schiele participated in numerous group exhibitions, including those of the Neukunstgruppe in Prague in 1910 and Budapest in 1912; the Sonderbund, Cologne, in 1912; and several Secessionist shows in Munich, beginning in 1911. In 1913, the Galerie Hans Goltz, Munich, mounted Schiele's first solo show. A solo exhibition of his work took place in Paris in 1914.

In the autumn of 1918, the Spanish flu pandemic that claimed more than 20,000,000 lives in Europe reached Vienna. Edith, who was six months pregnant, succumbed to the disease on 28 October. Schiele died only three days after his wife. He was 28 years old. During the three days between their deaths, Schiele drew a few sketches of Edith; these were his last works.

In his early years, Schiele was strongly influenced by Klimt and Kokoschka. Although imitations of their styles, particularly with the former, are noticeably visible in Schiele's first works, he soon evolved into his own distinctive style.

Some view Schiele's work as being grotesque, erotic, pornographic, or disturbing, focusing on sex, death, and discovery. He focused on portraits of others as well as himself. In his later years, while he still worked often with nudes, they were done in a more realist fashion. He also painted tributes to Van Gogh's Sunflowers as well as landscapes and still lifes.
