A friend asked me to answer this question: What is the first name of the person who was friends with Pirckheimer?, using the article: 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..., what would be the answer ?
