Philipp Franz Balthasar von Siebold (born February 17, 1796 – died October 18, 1866) was a German doctor, plant expert, and explorer. He became famous for studying the plants and animals of Japan. He also helped bring Western medicine to Japan. His daughter, Kusumoto Ine, became the first Japanese woman to be trained as a Western doctor.

Becoming a Doctor and Explorer

Philipp Franz von Siebold was born in Würzburg, Germany. His family had many doctors and professors. He studied medicine at the University of Würzburg starting in 1815. One of his teachers, Ignaz Döllinger, taught him to see medicine as a natural science. Siebold was inspired by the books of Alexander von Humboldt, a famous explorer. He earned his medical degree in 1820.

In 1822, Siebold joined the Dutch military as a ship's surgeon. He sailed from Rotterdam to Batavia (now Jakarta) in what is now Indonesia. On this long trip, he learned the Dutch and Malay languages. He also started collecting sea animals.

Arriving in Japan

In 1823, Siebold was sent to Dejima. This was a small, artificial island and trading post in Nagasaki, Japan. At that time, Japan had very strict rules. Only a few Dutch people were allowed to live on Dejima. Siebold was chosen to be both the doctor and a scientist there. He arrived on August 11, 1823.

Earlier, other European doctors and plant experts like Engelbert Kaempfer and Carl Peter Thunberg had also visited Japan. They helped start the tradition of sending doctors with knowledge of plants to Japan.

Siebold's Work in Japan

Bringing Western Medicine to Japan

Japanese scientists were very interested in Western science. They invited Siebold to share his knowledge. In return, he learned a lot about Japan and its customs. After he successfully treated an important local officer, he was allowed to leave the trading post. This let him treat Japanese patients in the area around Dejima. Siebold is known for bringing vaccination and modern anatomy studies to Japan for the first time.

In 1824, Siebold opened a medical school in Nagasaki called the Narutaki-juku. About fifty students came to learn from him. These students also helped him with his studies of plants and nature. For many years, Dutch became the common language for scientific discussions in Japan.

People often paid Siebold with interesting objects and artifacts. These everyday items later became a huge collection of Japanese household goods, art, tools, and crafts.

His Japanese Family

While in Japan, Siebold had a family with Kusumoto Taki. Their daughter, Kusumoto Ine, was born in 1827. Siebold called Kusumoto Taki "Otakusa" and even named a type of Hydrangea flower after her. Kusumoto Ine grew up to be the first Japanese woman to become a trained doctor. She became a highly respected physician and even served the Japanese Empress in 1882.

Studying Japanese Nature

Siebold was most interested in studying Japan's plants and animals. He collected as much material as he could find. He started a small garden behind his home on Dejima. There, he gathered over 1,000 native plants. He even built a special greenhouse to help Japanese plants get used to the Dutch climate.

Japanese artists, like Kawahara Keiga, drew and painted these plants for him. They also drew pictures of daily life in Japan, which added to Siebold's collection of Japanese objects. He hired Japanese hunters to find rare animals and collect samples. Many Japanese helpers, including doctors and botanists, assisted him. His assistant, Heinrich Bürger, also continued Siebold's work in Japan.

Siebold introduced many well-known garden plants to Europe. These include the Hosta and the Hydrangea otaksa. He also secretly sent tea plant seeds to a botanical garden in Batavia. This single act helped start the tea industry in Java, which was a Dutch colony at the time. Before this, Japan strictly controlled the trade of tea plants. By 1833, Java already had half a million tea plants.

He also brought Japanese knotweed to Europe. This plant has since become a very invasive weed in Europe and North America. All these plants came from a single female plant that Siebold collected.

Siebold sent many plant and animal samples to Europe. These included the first Japanese giant salamander specimens ever sent to Europe.

The Siebold Incident

In 1826, Siebold traveled to Edo (now Tokyo) to visit the Japanese court. During this long trip, he collected many plants and animals. But he also got some secret maps of Japan and Korea from the court astronomer. This was strictly forbidden by the Japanese government.

When the Japanese accidentally found out Siebold had these maps, they accused him of being a spy. They believed he was working for Russia. Siebold was placed under house arrest. On October 22, 1829, he was expelled from Japan. He returned to Batavia with his huge collection of animals, plants, books, and maps. He arrived in the Netherlands in 1830.

Siebold's Return to Europe

When Siebold arrived in the Netherlands, he quickly moved his collections to Leiden. He left some living plant collections in Ghent, which helped that city become famous for its gardens.

Siebold settled in Leiden with most of his collection. His "Philipp Franz von Siebold collection" was the first large collection of Japanese plants in Europe. It had about 12,000 samples. The Dutch government bought this entire collection. Siebold was also given money each year by the Dutch King William II. He was made an "Advisor to the King for Japanese Affairs." In 1842, the King even made Siebold a nobleman.

The "Siebold collection" opened to the public in 1831. In 1837, he started a museum in his home. This small museum later became the National Museum of Ethnology in Leiden. Siebold's successor in Japan, Heinrich Bürger, sent him even more plant samples. These collections are now part of the Naturalis Biodiversity Center, a large natural history museum in the Netherlands.

In 1845, Siebold married Helene von Gagern. They had three sons and two daughters.

His Important Books

While in Leiden, Siebold wrote a major work called Nippon starting in 1832. This book was about Japan's culture and geography. It had many beautiful illustrations. He also wrote Flora Japonica with another botanist, Joseph Gerhard Zuccarini. This book, published between 1835 and 1870, made Siebold famous in Europe for his scientific work.

Many plants from Siebold's collections spread from the Hortus Botanicus Leiden (Leiden's botanical garden) to other gardens around the world. These include Hosta, Hortensia, Azalea, and the Japanese larch.

Later Years and Legacy

After returning to Europe, Siebold tried to use his knowledge of Japan. He even advised the Russian government on how to trade with Japan. He also spoke with American Naval Commodore Matthew C. Perry before Perry's famous trip to Japan in 1854.

In 1858, the Japanese government allowed Siebold to return. He went back to Japan in 1859 as an adviser. However, his advice was not always valued, and he eventually returned to Europe. He tried to get another job as a consul in Japan but was unsuccessful. Philipp Franz von Siebold died in Munich on October 18, 1866.
