The institution which was at first called the "Museum Japonicum". It was the first museum in Europe which was designed to demonstrate that collecting the artefacts of man could mean more than the mere accumulation of curiosities. From the very outset, this innovative institution incorporated at least four basic principles: collecting, scientific research, presentation to the public, and educational guidance. In 1816 the Koninklijk Kabinet van Zeldzaamheden was formed in the Hague as an attempt to start a museum of scientific artifacts from around the world, based on royal collections and a large group of Chinese artifacts from private collections. Thanks to the early efforts of this organization, in the early 1830s, when Philipp Franz Balthasar von Siebold abandoned the political turmoil of revolutionary Belgium for the relative calm of the University of Leiden, he was inspired by the first museum director R.P. van de Kasteele to collect Japanese objects for his collection. The resulting gift of about 5,000 objects became the heart the new museum's holdings. Siebold's home in Leiden—and the objects he brought to Europe after eight years in Japan—was opened to the public in the early 1830s. The Dutch crown had previously purchased the smaller collections of Jan Cock Blomhoff in 1826 and Johannes Gerhard Frederik van Overmeer Fischer in 1832. These which were merged with what Siebold bestowed on King William I; and they became crucial elements in the creation of what became the Museum voor Volkenkunde, or Ethnographic Museum in Leiden in 1837. This institution would later evolve into the National Museum of Ethnology. In 1843, Siebold also encouraged other Europeans to create ethnographic institutions similar to what was developing in Leiden. He urged "the importance of their creation in European states possessing colonies because these institutions could become a means for understanding the subject peoples and of awakening the interest of the public and of merchants -- all of which are necessary conditions for a lucrative trade which benefits all."
Museum holdings
The collection today contains a large number of objects from Africa, China, Indonesia, Japan, Korea, Latin America, North America, Oceania, and Asia. In developing the collection, the museum has devoted significant attention to acquiring material which illustrates the historical development of world cultures; but the genesis of the museum's holdings began with material garnered during the years Japan was officially closed except for one small island in Nagasaki harbor -- Dejima.
Blomhoff collection
As Opperhoofd for the Dutch East India Company at Dejima island in Nagasaki harbor from 1817 through 1823, Jan Cock Blomhoff was unique. Despite the Japanese "closed door" policy for Westerners, he did transport his wife, Titia, and children to join him. The Japanese predictably responded by ejecting both Blomhoff and his family; but that experience did broaden the range of household goods and other objects he accumulated across the span of his stay in Japan.
Fischer collection
Johannes Gerhard Frederik van Overmeer Fischer began as a clerk at Dejima and he was later promoted to "Package House Master". During the span of his stay in Japan, Fisher's access to Japanese culture was limited; but within his universe of contacts, he was able to amass a considerable collection of "ordinary" objects which were plausbily overlooked by others. This material was brought back to the Netherlands in 1829. In 1833, he published Bijdrage tot de kennis van het Japansche rijk.
Siebold collection
As a physician practicing Western medicine in Nagasaki, Philipp Franz von Siebold received payment in kind with a variety of objects and artifacts which would later gain unanticipated scholarly attention in Europe. These everyday objects later became the basis of his large ethnographic collection, which consisted of everyday household goods, woodblock prints, tools and hand-crafted objects used by the Japanese people in the late Edo period. Further information relating to this material was published in Siebold's Nippon. His professional interest was especially drawn to implements used in the practice of traditional Japanese medicine. As of 2005, a separate museum located in one of Siebold's former houses, the SieboldHuis, houses part of the collection.
