remaining Dürer collections and papers. Most of Pirckheimer's own library, famous in its day, was sold by another Imhoff descendant to the Earl of Arundel in 1636. Most of the Arundel library was given to the Royal Society in 1678. Some of Pirckheimer's books therefore remain there (85 have been identified), but many more were sold out of the Royal Society, firstly to Bernard Quaritch in 1873, and secondly via Sotheby's in 1925. Pirckheimer was also a patron of the astronomist and meteorologist Johannes Werner. Werner relied on the support from Pirckheimer, Sebald Schreyer and others to develop his instruments and make systematic experiments and observances in measuring distances and locations, study the earth's magnetism and meteorology. Pirckheimer died in Nuremberg, aged 60. Like Dürer, he is buried in the cemetery of the Johannis-kirche in Nuremberg. A portrait of Pirckheimer appears on the 100 Billion Mark note issued during Germany's Weimar Republic.
