Rip Van Winkle

     "Rip Van Winkle" is a short story by American author Washington Irving published in 1819 as well as the name of the story's fictional protagonist.

       Rip Van Winkle is descended from gallant soldiers but is a peaceful man himself, known for being a kind and gentle neighbor. His single flaw is an utter inability to do any work that could turn a profit. It is not because he is lazy—in fact, he is perfectly willing to spend all day helping someone else with their labor. He is just incapable of doing anything to help his own household. He also is well-known for being an obedient, henpecked husband, for Dame Van Winkle has no problem shouting insults into the neighborhood and tracking him down in the village to berate him. All the women and children in the village love him and side with him against his wife, and even the dogs do not bark at him.

     Vincent Willem van Gogh ( 30 March 1853 – 29 July 1890) was a Dutch post-Impressionist painter whose work had far-reaching influence on 20th-century art. His paintings include portraits, self portraits, landscapes, still lifes of cypresses, wheat fields and sunflowers. Van Gogh was born to upper middle class parents and spent his early adulthood working for a firm of art dealers before traveling to The Hague, London and Paris, after which he taught in England at Isleworth and Ramsgate. He drew as a child but did not paint until his late twenties; most of his best-known works were completed during the last two years of his life. In just over a decade, he produced more than 2,100 artworks, including 860 oil paintings and more than 1,300 watercolors, drawings, sketches and prints.
