Task: Question Generation
Input (English): Passage: Thomson was largely self-taught. His experiences as a graphic designer with Toronto's Grip Ltd. honed his draughtsmanship. Although he began painting and drawing at an early age, it was only in 1912, when he was well into his thirties, that he began to paint seriously. His first trips to Algonquin Park inspired him to follow the lead of fellow artists in producing oil sketches of natural scenes on small, rectangular panels for easy portability while travelling. Between 1912 and his death in 1917, Thomson produced hundreds of these small sketches, many of which are now considered works in their own right, and are mostly found in the Art Gallery of Ontario in Toronto, the National Gallery of Canada in Ottawa, the McMichael Canadian Art Collection in Kleinburg and the Tom Thomson Art Gallery in Owen Sound.Thomson produced nearly all of his works between 1912 and 1917. Most of his large canvases were completed in his most productive period, from late 1916 to early 1917. The patronage of James MacCallum enabled Thomson's transition from graphic designer to professional painter. Although the Group of Seven was not founded until after his death, his work was sympathetic to that of group members A. Y. Jackson, Frederick Varley, and Arthur Lismer. These artists shared an appreciation for rugged, unkempt natural scenery, and all used broad brush strokes and a liberal application of paint to capture the beauty and colour of the Ontario landscape. Thomson's art also bears some stylistic resemblance to the work of European post-impressionists such as Vincent van Gogh. Other key influences were the Art Nouveau and Arts and Crafts movements of the late nineteenth and early twentieth centuries, styles with which he became familiar while working in the graphic arts.
Output (English): What are the names of the artists that shared an appreciation for rugged, unkempt natural scenery, and all used broad brush strokes and a liberal application of paint to capture the beauty and colour of the Ontario landscape?
