Egon Schiele was born in 1890. His youth was troubled and withdrawn, and his peers thought him strange. Except for art class and sports, school was difficult. His sister, Gerti, four years younger, was an object of conflicted desire; when Schiele was 16 he took her to Trieste, where they spent the night in a hotel room. And then he found painting. In 1907, Schiele sought guidance from Gustav Klimt; two years later he was exhibiting work at the Vienna Kunstschau. Schiele’s art undressed dark and nervous thoughts. Wayward sexual desire and frank physicality permeated his canvases. Schiele died in the 1918 flu pandemic, still a young artist at 28 (his pregnant wife died three days before him). This exhibition looks at the completely original work he produced in his short life. —E.C.
