Philipp Franz von Siebold, a German physician, botanist, and traveler, made a lasting mark on the scientific world during the 19th century. His journeys to Japan were impactful, bridging the gap between Western scientific knowledge and the then-isolated nation. Siebold’s work in collecting and documenting Japanese flora, fauna, and cultural artifacts is widely recognized.
Arrival and Contributions in Japan
Philipp Franz von Siebold arrived in Japan in 1823, serving as a physician for the Dutch trading post located on Dejima in Nagasaki Bay. Although foreigners were typically restricted to Dejima, Siebold’s medical expertise allowed him special permission to treat Japanese patients outside the island. He leveraged this unique access to introduce Western medical practices, including surgical techniques and vaccinations, to Japan.
In 1824, Siebold established a medical school and clinic in Narutaki, Nagasaki, known as Narutaki-juku. This institution became a hub for about fifty Japanese students learning Western medicine and natural sciences. His students assisted him in his botanical and naturalistic studies, contributing to his collections.
Siebold’s primary scientific interest lay in studying Japanese flora and fauna. He cultivated a botanical garden on Dejima, where he amassed over 1,000 native plants. He also hired Japanese hunters to collect animal specimens and collaborated with Japanese artists like Kawahara Keiga, who created detailed botanical illustrations and images of daily life, complementing his ethnographic collections. Through his interactions with students and patients, Siebold also gathered ethnographic specimens and artifacts, which later formed collections in Europe.
The Siebold Incident and Its Aftermath
The “Siebold Incident” unfolded in 1828, leading to his expulsion from Japan. A Dutch trading ship carrying some of Siebold’s belongings ran aground in Nagasaki Bay during a storm. Japanese authorities, inspecting the damaged vessel, discovered maps of Japan, plans of Edo Castle, and surveys of Sakhalin among his possessions.
The possession of such detailed maps and sensitive geographical information was forbidden by the Japanese government. Siebold was accused of illegally obtaining these documents and, by some accounts, of spying for Russia. His collaborators, including the shogunate’s official geographer Takahashi Gensuke, were arrested.
Siebold was placed under house arrest and, in October 1829, was expelled from Japan and forbidden to return. Many of his collected items were confiscated, though he returned to Europe with a substantial portion of his collections. Despite the lifetime ban, Siebold later returned to Japan for a second, albeit short-lived, visit after the ban was lifted in 1858.
Enduring Legacy
Philipp Franz von Siebold’s work left a lasting impact, particularly in botany, zoology, and cultural exchange. His botanical and zoological collections from Japan formed the basis for scientific studies and enriched European museums, such as the Naturalis Biodiversity Center in Leiden. His documented specimens were instrumental in producing “Fauna Japonica” and “Flora Japonica,” which introduced Japanese species to the Western world.
Numerous plant and animal species have been named in his honor, including Siebold’s magnolia (Magnolia sieboldii) and Siebold’s viburnum (Viburnum sieboldii). His influence on Japanese science and medicine was substantial, as his students propagated Western knowledge, contributing to Japan’s modernization. Furthermore, his collections and publications fostered ongoing academic and cultural exchange between Japan and the West. Museums like the Japan Museum SieboldHuis in Leiden and the Siebold Memorial Museum in Nagasaki preserve his memory and showcase his collections.
