A quote from an article I found concerning this German expedition during the second World war:
Furthermore, a German expedition of 1942 enabled F. Dölger and his associates to record on film the great collection of monastic charters, property deeds and chrysobuls which completed a task initiated as early as 1857 when Russian scholar, P. I. Sevastianov, did the first photographing of manuscripts at Athos.
Another picture of Hitler on Athos in Panteleimonos.

Dölger also got the rare opportunity to study the “Tragos” in the library in Karyes !
