フィリップ・フランツ・フォン・シーボルト
Another major contribution to the collections was made by Philipp Franz von Siebold, a German physician who was employed on Deshima (Japan) by the VOC from 1823 until his expulsion by Japan in 1829. During that period he collected many dried and living plants from all over Japan (as well as animals, ethnographical objects, maps, etc.), and sent them to Leiden.
