February 12, 1850 - February 5, 1934,Davis, who was born in Philadelphia, Pennsylvania, was educated at Harvard. He returned to teach there in 1877 after a period as a meteorologist in Argentina and as an assistant with the North Pacific Survey. He became professor of physical geography in 1890 and of geology in 1898. Davis is acknowledged as the founder of geomorphology, the study of landforms. In his The Rivers and Valleys of Pennsylvania (1889) he first introduced what later became known as the Davisian systems of landscape analysis. His aim was to provide an explanatory description of how landforms change in an ideal situation and his most important contribution to this was his introduction of the cycle of erosion into geographical thought. He proposed a complete cycle of youth, maturity, and old age to describe the evolution of a landscape. In youth rivers occupy steep V-shaped valleys while in old age the valleys are broad. The end product would be a flat featureless plain he called a epeneplaine. This was an ideal cycle but in practice the cycle would invariably be interrupted by Earth movements. It was, nevertheless, strongly attacked by German geographers who objected to it on the grounds that it neglected such vital factors as weathering and climate in transforming the landscape. They also believed him to be undermining their argument that landforms could only be discovered by local fieldwork and the production of regional monographs. Davis also produced an influential work,  Related Paintings of William Morris Davis :. | John the Baptist | Portrait of a man,hean and shoulders,wearing black with a white lace collar | Self-Portrait | The Annunciation | the morning hour |

Antonio Bellucci
Antonio Bellucci (1654-1726) was an Italian painter of the Rococo period, who was best known for his work in England, Germany, and Austria. He was one of the many Venetian-trained artists of his time, including Ricci, Tiepolo, Amigoni, and others, who sought commissions north of Italy, providing patrons with the then-popular Italianate grand-manner frescoes for private palaces.
Francisco Jose de Goya
Spanish Rococo Era/Romantic Painter and Printmaker, 1746-1828 Goya is considered the 18th Century's foremost painter and etcher of Spanish culture, known for his realistic scenes of battles, bullfights and human corruption. Goya lived during a time of upheaval in Spain that included war with France, the Inquisition, the rule of Napoleon's brother, Joseph, as the King of Spain and, finally, the reign of the Spanish King Ferdinand VII. Experts proclaim these events -- and Goya's deafness as a result of an illness in 1793 -- as central to understanding Goya's work, which frequently depicts human misery in a satiric and sometimes nightmarish fashion. From the 1770s he was a royal court painter for Charles III and Charles IV, and when Bonaparte took the throne in 1809, Goya swore fealty to the new king. When the crown was restored to Spain's Ferdinand VII (1814), Goya, in spite of his earlier allegiance to the French king, was reinstated as royal painter. After 1824 he lived in self-imposed exile in Bordeaux until his death, reportedly because of political differences with Ferdinand. Over his long career he created hundreds of paintings, etchings, and lithographs, among them Maya Clothed and Maya Nude (1798-1800); Caprichos (1799-82); The Second of May 1808 and The Third of May 1808 (1814); Disasters of War (1810-20); and The Black Paintings (1820-23).
