Question: What is the name of Albrecht the Elder's son?
Answer: Dürer
Barbara Holper was the daughter of Hieronymus Holper, under whom Albrecht the Elder served his apprenticeship as a goldsmith. The two men became friends, and when she came of age Holper gave his daughter into marriage when Dürer senior was 40 and she was 15. The couple were compatible, well-matched and fond of each other. Yet their son's writings detail their difficult lives and many setbacks; three of their 18 children survived into adulthood – 17 of whom had been born by the time of this portrait. After her husband died Barbara was destitute and went to live with her son. After she in turn died in 1514, her son wrote "This my pious Mother ... often had the plague and many other severe and strange illnesses, and she suffered great poverty, scorn, contempt, mocking words, terrors, and great adversities. Yet she bore no malice. Also she died hard ... I felt so grieved for her that I cannot express it."
Barbara is shown wearing a red dress and a matte white bonnet which fully covers her hair, indicating her marital status. Her headdress is draped with a long scarf or train which stretches down her neck and across her left shoulder, contrasting in colour and shape against the black head-wear of her husband. The lines of her face contain touches of white paint to give a highlighting and enlivening effect; they are especially evident around her eyes, the bridge of her nose and around her upper lip. Barbara was attractive in her youth; her son described her as having been "comely and of erect bearing". However, by the time of this portrait the effects of time and losing so many children weigh heavily on her face. The panel was grounded with white paint, while the composition seems to have changed significantly from the  imprimatura. Faint traces of the original figuration are visible in parts of the background and in the darkened areas of her hood. At some point the panel was cut down at the left side, shifting the compositional balance and removing a portion of her shoulder and headdress.

Question: What is the first name of the person whose husband died first?
Answer: Barbara
Dürer's father wears a dark shirt, russet coat and a black hat lined with fur. His skin is slack at the mouth and chin, and he has small, intelligent eyes, which Von Fircks describes as "dark and serious". Their curves echo those of the heavy lids beneath. His eyes are lined with crow's feet and shadowed with brown hatched paint. His facial features are built from brush strokes more typical of drawing than painting—at this young age Dürer was a far more skilled draughtsman than painter. Technical analysis carried out in 2013 by Dagmar Hirschfelder revealed a detailed background which was over-painted by the artist. The abandoned interior space consisted of a corner of a room with an arched window looking out to a countryside view. This type of interior can be traced to the Netherlandish tradition, and is rare in German portraiture of the period.
Albrecht the Elder's lips are thin and tightly pursed and his mouth is broad and down-turned, yet his features are those of a handsome man. Marcel Brion described him as appearing "mild and thoughtful", an impression reinforced by the uncomplicated design of the painting. This view is reinforced by the relative drabness or simplicity of his clothes, which seem intended to convey a reserved, ascetic piousness. Dürer presents his father more like a low-ranking  ecclesiastic than a tradesman: a calm, considerate and straightforward man dressed up in his best, albeit modest, clothes. After his father's death in 1502, Dürer wrote that Albrecht the Elder "passed his life in great toil and stern hard labour, having nothing for his support save what he earned with his hand for himself, his wife and his children ... He underwent manifold afflictions, trials and adversities. But he won just praise from all who knew him ... he was also of few words, and was a God-fearing man."Martin Conway describes the portrayal of a dignified man marked by a grave expression and deep "furrows ploughed by seventy years of labour and sorrow". Conway believed the strength of the portrait is in part achieved through Dürer's ability to convey this hardship, while at the same time presenting a man still imbued with traces of pride, and possessing "a kind old face". Noting the obvious affection between the father and son as well as the half smile of the older man, he wonders if that grin might have been born of Albrecht the Elder's satisfaction that his toil has been rewarded by a son of such talent, who was now about to set out on the world for his wanderjahr. A contributing factor to this pride is that Albrecht the Elder trained his son in his own profession, as a jeweller, but at one point came to regret the choice of apprenticeship as the younger man was so obviously suited to drawing and painting. However, his son learned many skills during that period and it gave him a discipline with his hands that became a defining factor of his work, especially in his ability as an engraver.

The abandoned interior space consisted of a corner of a room with an arched window looking out to a countryside view. This type of interior can be traced to the Netherlandish tradition, and is rare in German portraiture of the period.
Albrecht the Elder's lips are thin and tightly pursed and his mouth is broad and down-turned, yet his features are those of a handsome man. Marcel Brion described him as appearing "mild and thoughtful", an impression reinforced by the uncomplicated design of the painting. This view is reinforced by the relative drabness or simplicity of his clothes, which seem intended to convey a reserved, ascetic piousness. Dürer presents his father more like a low-ranking  ecclesiastic than a tradesman: a calm, considerate and straightforward man dressed up in his best, albeit modest, clothes. After his father's death in 1502, Dürer wrote that Albrecht the Elder "passed his life in great toil and stern hard labour, having nothing for his support save what he earned with his hand for himself, his wife and his children ... He underwent manifold afflictions, trials and adversities. But he won just praise from all who knew him ... he was also of few words, and was a God-fearing man."Martin Conway describes the portrayal of a dignified man marked by a grave expression and deep "furrows ploughed by seventy years of labour and sorrow". Conway believed the strength of the portrait is in part achieved through Dürer's ability to convey this hardship, while at the same time presenting a man still imbued with traces of pride, and possessing "a kind old face". Noting the obvious affection between the father and son as well as the half smile of the older man, he wonders if that grin might have been born of Albrecht the Elder's satisfaction that his toil has been rewarded by a son of such talent, who was now about to set out on the world for his wanderjahr. A contributing factor to this pride is that Albrecht the Elder trained his son in his own profession, as a jeweller, but at one point came to regret the choice of apprenticeship as the younger man was so obviously suited to drawing and painting. However, his son learned many skills during that period and it gave him a discipline with his hands that became a defining factor of his work, especially in his ability as an engraver.

Question: What is the last name of the person who wonders if the grin might have been born of Albrecht the Elder's satisfaction that his toil has been rewarded by a son of such talent?
Answer: Conway
After the painter's death in 1528, the portraits were held by his brother, and then his brother's widow before they passed into the collection of Willibald Imhoff, a grandson of Dürer's friend Willibald Pirckheimer. Inventories from the Imhoff collection from 1573–74, 1580 and 1588 list both panels. The next surviving Imhoff inventory, of 1628, again lists the mother's portrait, but it disappears after mention in the 1633–58 account books of Hans Hieronymus Imhoff, after which its whereabouts became unknown. Dürer expert Matthias Mende described the missing portrait of Barbara Holper as "among the most severe losses in the Dürer oeuvre".
In 1977, art historian Lotte Brand Philip proposed that Unknown Woman in a Coif, held by the Germanisches Nationalmuseum in Nuremberg, was the original portrait of Barbara Holper. The Nuremberg panel was previously thought to have originated from a member of Wolgemut's workshop, a Franconian artist in his circle, or the anonymous Mainz painter Master W. B. Brand Philip's attribution was based on striking similarities in composition and its shared tone, theme and size with the father panel at the Uffizi. In both works the sitters are holding rosary beads, and Dürer attentively describes their hands. Both portraits show the sitter in the same pose, against a similarly coloured background. Both are lit from the upper left. The boards are identically cut in width and depth, although 3 cm was removed from the left edge of Barbara's panel. Brand Philip noted the similarities between the panel and Dürer's 1514 charcoal drawing Portrait of the Artist's Mother at the Age of 63. Fedja Anzelewsky agreed with the attribution, noting that both portraits bear, on their reverse, the catalogue number recorded in the Imhoff inventories, as well as "precisely the same design of masses of dark clouds".Anzelewsky speculated that the father's portrait, which was not listed in the 1628 Imhoff inventory, had been broken off and sold to Rudolph II of Austria. Hans Hieronymus Imhoff's lukewarm description of Barbara's portrait—"the mother of Albrecht Dürer in oil colors on wood, [but] there are many who do not believe it to be a work of Dürer"—led Brand Philip to conclude that Albrecht's panel was likely sold individually as the more accomplished and marketable of the two. The attribution is widely accepted today. In 2013 Stephan Kemperdick noted the sophistication of the Nuremberg portrait and that its three-dimensional modeling of the head displays a level of skill beyond Wolgemut and his circle.The two panels were reunited in 2012 during a Dürer exhibition in Nuremberg having been separated since sometime between 1588 and 1628.
