Nils Seethaler was born in Berlin-Lichterfelde and spent his youth in Berlin, Rocky Point (Australia) and in Morschen in northern Hesse (Germany).
The Canadian doctor William Osler brought the skulls to Germany at the end of the 19th century and gave them to Rudolf Virchow in Berlin.
[11] In addition to his work with historical collections, Seethaler was involved in a number of interdisciplinary research at the interface between the humanities and the natural sciences.
[16] Seethaler advised, organized and directed numerous museum exhibition projects on ethnological, art-historical and natural science topics.
[17] The opening of the cross-cultural exhibition "Objects of Adoration" ("Objekte der Verehrung") conceived by Seethaler was the finale of the internationally received events for the Reformation anniversary in 2017 in Lutherstadt Wittenberg.
