John Singer Sargent (/ˈsɑrdʒənt/; January 12, 1856 – April 14, 1925) was an American artist, considered the "leading portrait painter of his generation" for his evocations of Edwardian era luxury. During his career, he created roughly 900 oil paintings and more than 2,000 watercolors, as well as countless sketches and charcoal drawings. His oeuvre documents worldwide travel, from Venice to the Tyrol, Corfu, the Middle East, Montana, Maine, and Florida. (wikipedia, wikipedia.org/wiki/John_Singer_Sargent)
Arthur Rackham (19 September 1867 – 6 September 1939) was an English book illustrator. Arthur Rackham is widely regarded as one of the leading illustrators from the 'Golden Age' of British book illustration which encompassed the years from 1900 until the start of the First World War. During that period, there was a strong market for high quality illustrated books which typically were given as Christmas gifts. Many of Rackham's books were produced in a de luxe limited edition, often vellum bound and sometimes signed, as well as a larger, less ornately bound quarto 'trade' edition. This was often followed by a more modestly presented octavo edition in subsequent years for particularly popular books. The onset of the war in 1914 curtailed the market for such quality books, and the public's taste for fantasy and fairies also declined in the 1920s. Arthur Rackham's works have become very popular since his death, both in North America and Britain. His images have been widely used by the greeting card industry and many of his books are still in print or have been recently available in both paperback and hardback editions. His original drawings and paintings are keenly sought at the major international art auction houses.(wikipedia, wikipedia.org/wiki/Arthur_Rackham)
Caspar David Friedrich (September 5, 1774 – May 7, 1840) was a 19th-century German Romantic landscape painter, generally considered the most important German artist of his generation. He is best known for his mid-period allegorical landscapes which typically feature contemplative figures silhouetted against night skies, morning mists, barren trees or Gothic ruins. His primary interest as an artist was the contemplation of nature, and his often symbolic and anti-classical work seeks to convey a subjective, emotional response to the natural world. Friedrich's paintings characteristically set a human presence in diminished perspective amid expansive landscapes, reducing the figures to a scale that, according to the art historian Christopher John Murray, directs "the viewer's gaze towards their metaphysical dimension".
