Paul Julius Arndt (14 October 1865 – 17 July 1937) was a German classical archaeologist born in Dresden.
Following Brunn's death in 1894, Arndt became an assistant to Adolf Furtwängler (1853-1907), and was responsible for edition of "Denkmäler griechischer und römischer Skulptur".
Arndt was the son of a wealthy merchant in Mecklenburg, and for much of his career was financially independent, therefore having the means to work as a private scholar and dealer of Greek art.
[1] He was primarily known as a collector of ancient sculptures, a large part of which are now kept in the Glyptothek of Munich, as well as in Ny Carlsberg Glyptotek, Copenhagen.
Arndt's scientific estate is owned by the Institute of Classical Archaeology of the University of Erlangen.
