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 :. | St George and the Dragon (detail) sdgf | Charles I with M. de St Antoine | St Luke Painting the Madonna by Jan Mabuse | Adoration of the Shepherds | Mattia Preti the guest meal Abschaloms |

Pietro Antonio Rotari
Italian painter , (b. 1707, Verona, d. 1762, St. Petersburg) Italian painter. His artistic career began as a youthful distraction, but his talent quickly became apparent, and he entered the studio of Antonio Balestra in Verona, remaining there until he was 18. He spent the years 1725-7 in Venice and then moved c. 1728 to Rome, where he stayed for four years as a student of Francesco Trevisani. Between 1731 and 1734 he studied with Francesco Solimena in Naples before returning to Verona, where he set up his own studio and school. His most notable early independent works are multi-figured altarpieces (e.g. the Four Martyrs, 1745; Verona, church of the Ospedale di S Giacomo), which emulate 17th-century Roman and Neapolitan works. However, he also studied the smaller, more intimate paintings of Roman Baroque artists, and these influenced his later works. He fell victim to the wanderlust that appears to have been endemic to 18th-century Venetian painters, and c. 1751 he travelled to Vienna, where he was able to study works by Jean-Etienne Liotard, whose clean pictorial smoothness impressed him. He later moved to Dresden

Johan Gustaf Sandberg, född 1782, död 1854, var målare; han var professor i teckning vid Konstakademien från 1828, och direktör där 1845?C1853. Sandberg ägnade sig främst åt historiemåleri, med motiv ur nordisk mytologi och svensk historia. Hans främsta verk inom detta område är kalkmålningarna över Gustav Vasa i Uppsala domkyrka. Han målade också en mängd porträtt. Sandberg blev 1794 elev i konstakademins principskola och 1801 i antikskolan, lärde samtidigt musik och klaverspelning och tjänade pengar genom lektioner och genom arbete på kungliga teaterns dekorationsmålarverkstad. Under den följande tiden slöt han sig till den opposition mot akademin, som hade sin medelpunkt i "Sällskapet för konststudium". Tvisten med akademin lade sig snart, Sandberg valdes till ledamot 1821 och blev ordinarie professor 1828. Däremot hade han aldrig tillfälle att göra den för äldre tiders konstnärer obligatoriska studieresan till södern. Han utförde teckningarna till praktverket "Ett år i Sverige" (1827 -35) med bilderna graverade under Christian Didrik Forssells ledning och texten skriven av Anders Abraham Grafström. Under upprepade sommarvistelser på Säfstaholms slott målade Sandberg folktyper och folkdräkter. Åtskilliga porträtt utförde Sandberg för det praktfulla "Galleri af utmärkta svenska lärde, vetenskapsidkare och konstnärer", som han utgav 1835?C42 (100 porträtt, litograferade av J. Cardon).
