Washington Irving (April 3, 1783 - November 28, 1859) was an American short story writer, essayist, biographer, historian, and diplomat of the early 19th century. He is best known for his short stories "Rip Van Winkle" (1819) and "The Legend of Sleepy Hollow" (1820), both of which appear in his book The Sketch Book of Geoffrey Crayon, Gent. His historical works include biographies of George Washington, Oliver Goldsmith and Muhammad, and several histories of 15th-century Spain dealing with subjects such as Christopher Columbus, the Moors and the Alhambra. Irving served as the U.S. ambassador to Spain from 1842 to 1846. He made his literary debut in 1802 with a series of observational letters to the Morning Chronicle, written under the pseudonym Jonathan Oldstyle. After moving to England for the family business in 1815, he achieved international fame with the publication of The Sketch Book of Geoffrey Crayon, Gent. in 1819-20. He continued to publish regularly-and almost always successfully-throughout his life, and just eight months before his death (at age 76, in Tarrytown, New York), completed a five-volume biography of George Washington. Irving, along with James Fenimore Cooper, was among the first American writers to earn acclaim in Europe, and Irving encouraged American authors such as Nathaniel Hawthorne, Herman Melville, Henry Wadsworth Longfellow, and Edgar Allan Poe. Irving was also admired by some European writers, including Walter Scott, Lord Byron, Thomas Campbell, Francis Jeffrey, and Charles Dickens. As America's first genuine internationally best-selling author, Irving advocated for writing as a legitimate profession, and argued for stronger laws to protect American writers from copyright infringement. Randolph Caldecott ( 22 March 1846 - 12 February 1886) was an English artist and illustrator, born in Chester. The Caldecott Medal was named in his honour. He exercised his art chiefly in book illustrations. His abilities as an artist were promptly and generously recognised by the Royal Academy. Caldecott greatly influenced illustration of children's books during the nineteenth century. Two books illustrated by him, priced at a shilling each, were published every Christmas for eight years. Caldecott also illustrated novels and accounts of foreign travel, made humorous drawings depicting hunting and fashionable life, drew cartoons and he made sketches of the Houses of Parliament inside and out, and exhibited sculptures and paintings in oil and watercolour in the Royal Academy and galleries.
