Context: Christian Albrecht Jensen (26 June 1792 – 13 July 1870) was a Danish portrait painter who was active during the Golden Age of Danish Painting in the first half of the 19th century.  Painting more than 400 portraits over the course of his career, he depicted most of the leading figures of the Danish Golden Age, including the writer Hans Christian Andersen, the painter Christoffer Wilhelm Eckersberg, the sculptor Bertel Thorvaldsen, the physicist Hans Christian Ørsted and the theologian N. F. S. Grundtvig. James Bowman was an American itinerant artist and portrait painter.  He was born in Allegheny County, Pennsylvania near Pittsburgh.  Sometime between 1813 and 1815, James Bowman went to Chillicothe, Ohio, to learn to be a carpenter.  There he met the itinerant painter Mr. J. T. Turner who taught him the rudiments of portrait painting (such as mixing paints).  He gained considerable success when he started out professionally, painting in Pittsburgh and other communities in the early 1820s.  He traveled to Philadelphia to learn from the masters there, but as a beginning artist could not make a living in that more cosmopolitan and competitive environment and became an itinerant portrait painter instead. Hans Christian Ørsted ( ; ] ; often rendered Oersted in English; 14 August 17779 March 1851) was a Danish physicist and chemist who discovered that electric currents create magnetic fields, which was the first connection found between electricity and magnetism.  He is still known today for Oersted's Law.  He shaped post-Kantian philosophy and advances in science throughout the late 19th century. Heinrich Wilhelm Zimmerman, portrait painter, was born at Danzig in 1805.  In 1828 he went to Vienna, and thence, in 1835, to Paris, where he placed himself under Hippolyte Delaroche.  While in Paris he painted his "Sabbath Morning in Styria", a large work with twenty-six figures.  On his return to Danzig he practised chiefly as a portrait painter.  He died at Danzig in 1841. William Bell, born about 1734/5, was an English portrait painter originally from Newcastle upon Tyne.  In around 1768 he moved to London, to be a student in the Royal Academy of Arts.  While there, in the year of 1771, he received a gold medal for his painting of Venus entreating Vulcan to forge arms for her son Æneas.  William Bell's best known works were the portraits painted for the family of Delaval, of Seaton Delaval Hall.  These paintings earned Bell the patronage of Lord Delaval, and in 1775 he exhibited two views of Delaval Hall.  A portrait he painted of Robert Harrison, 1715-1802, is displayed in the National Portrait Gallery, London.  William Bell died on 8 June 1794 and was buried 10 June, St Andrew's Church, Newcastle upon Tyne; his death was reported in the Newcastle Courant (14 June 1794) thus: "DIED, Sunday morning, Mr William Bell, an eminent Portrait Painter, whose memory will be esteemed at long as his animated productions remain, many of which bear testimony to his abilities in this part of the kingdom". Bruce Corcoran , often known as Corky, is a recurring fictional character from the Jeeves novels of British comic writer P. G. Wodehouse, being a New York portrait painter turned cartoonist.  In the 1990s television series "Jeeves and Wooster" he is portrayed by Greg Charles .  Bruce Corcoran ("Corky"), a New York portrait painter turned cartoonist, asks Bertie to help him ask his wealthy uncle Alexander Worple to accept his girlfriend Muriel Singer so he can marry her.  In order to get Worple's blessings and to attract the affection of Corky's wealthy uncle, Jeeves produces a plan which involves Corky's girlfriend Muriel Singer writing a book, which pleases Worple.  At the end Jeeves writes "A Children’s Book of American Birds" in Muriel's place.  Things go wrong and the uncle ends up Corky's dream marrying her.  Alexander Worple marries Muriel Singer and Corky has only to paint a portrait of their baby.  But Worple dislikes Corky's Abstract Expressionist portrait painting of the baby and cuts off Corky's allowance.  Aunt Agatha comes with NY Chronicle Art Critic Arthur Prysock, an art critic with whom she wants to start and run her own art gallery.  She is enamoured of the Abstract Expressionist portrait painting by Bruce Corcoran ("Corky"), and asks NY Chronicle Art Critic Arthur Prysock to buy it for her art gallery. Guilliam van Deynum or Guilliam van Deynen (Antwerp, c. 1575 - Brussels, after 1624) was a Flemish painter, illuminator and miniaturist.  He was mainly a portrait artist.  After training in Antwerp he spent in the early 17th century a decade in Genoa where he was a successful portrait painter.  He returned to Flanders where he worked in Brussels as a portrait painter to the Governors of the Habsburg Netherlands Archduke Albert and the Infanta Isabella. Nathan Cooper Branwhite (c. 1775 – 18 March 1857) was an English miniature portrait painter, watercolourist and engraver who was a member of the Bristol School of artists.  He was Bristol's leading miniature portrait painter in the 1820s. Sir Henry Raeburn {'1': ", '2': ", '3': ", '4': "} ( ; 4 March 1756 – 8 July 1823) was a Scottish portrait painter and Scotland's first significant portrait painter since the Union to remain based in Scotland.  He served as Portrait Painter to King George IV in Scotland. Portrait of Dürer's Father at 70 (or The Painter's Father) is a 1497 oil on lime painting attributed to the German painter and printmaker Albrecht Dürer, now in the National Gallery, London.  Along with the 1490 "Albrecht Dürer the Elder with a Rosary", it is the second of two portraits of the artist's Hungarian father Albrecht Dürer the Elder (1427–1502).  The sitter's similarity to the earlier portrait, as well to a 1486 silverpoint drawing believed to be a self-portrait by his father, leave no doubt as to his identity.  The London panel is thought to be one of a number of copies of a lost original.  It is in poor condition, having suffered paint loss in the background and in areas of the cloak.  It was cleaned in 1955, revealing especial quality in the description of the face, leading some to believe that it is a Dürer original.  However this claim is not made by the National Gallery who display it as "attributed to Albrecht Dürer".
