You will be given a definition of a task first, then some input of the task.
In this task, you're given passages that contain mentions of names of people, places, or things. Some of these mentions refer to the same person, place, or thing. Your job is to write questions that evaluate one's understanding of such references. Good questions are expected to link pronouns (she, her, him, his, their, etc.) or other mentions to people, places, or things to which they may refer. Do not ask questions that can be answered correctly without understanding the paragraph or having multiple answers. Avoid questions that do not link phrases referring to the same entity. For each of your questions, the answer should be one or more phrases in the paragraph, and it should be unambiguous.

Passage: The three-quarter view was widely used in southern German portraiture of the late-15th century. Rosary beads were often included to indicate the piousness and modesty of the sitters, although by the 16th century religious motifs and sentiments like this were falling out of fashion. Durer distinguishes himself from his contemporaries through his tight and detailed focus on his parents' faces, a technique that draws comparison to the work of the first generation of Early Netherlandish painters active 50 years earlier. Albrecht the Elder had travelled to Flanders and from working with Netherlandish artists had acquired a strong appreciation for the work of both Jan van Eyck and Rogier van der Weyden. That he passed on this influence to his son is evident from the early use of silverpoint, a medium which according to Erwin Panofsky requires "an exceptional degree of confidence, accuracy and sensitive feeling for its successful handling".
Durer would have been aware of Hans Pleydenwurff's portrait of the ageing Count Georg von Lowenstein, through his teacher Michael Wolgemut. Pleydenwurff's portrait was in turn likely influenced by van Eyck's 1438 Portrait of Cardinal Niccolo Albergati. Von Fircks believes the portrait of Durer's father took from Pleydenwurff's portrait, which she describes as a "highly detailed representation of [a] white haired old man, who defies the pains of growing old with an alert mind and an inner animation".Von Fircks notes that Durer's 1484 self-portrait was created with the use of a mirror while his most iconic work is a self-portrait; the 1500 Self-Portrait at Twenty-Eight. From these she concludes that the "accurate observation and documentary recording" of both his own and his parents' appearances over time was not just a compulsion, but that is indicative of a deeper interest in the effects of time and age on human appearance. Although Durer was fascinated by the effects of ageing on others, he seems to have had some hesitancy at examining how it might affect him personally. The self-portraits tend to be idealised and the 1500 portrait was his last. Later self-portraits are far more understated and executed in a 'secondary' media, such as his drawings of the Man of Sorrows and nude drawing of 1505, which depicted an emaciated body during the time of the plague.
Output:
What was the full name of the person who concluded "accurate observation and documentary recording" of both his own and his parents' appearances over time was not just a compulsion, but that is indicative of a deeper interest in the effects of time and age on human appearance?
