Decipherment of the Letters(1821-1831) Concerning Phillipp Franz von Siebold

本研究的目的是对德国医生菲利普·弗朗茨·冯·西博尔德的文献资料进行解读和整理，并将其翻译成日语。这些材料主要由剩余的私人信件组成。西博尔德于1823年访问日本，并将现代科学引入日本。此外，他还在西方开创了对日本的科学研究。在冯·勃兰登斯坦家族(西博尔德的后代居住在德国)收藏的关于西博尔德的文件中，有写给西博尔德的信件和西博尔德在1822-1823年期间写的信件草稿。在我们研究的三年时间里，这些信件被取出、重印并翻译成日文。西博尔德在1822-1831年期间的信件也是以数据为基础的。结合这些数据，调查了确定他的伙伴的圈子所需的材料和到目前为止发表的他的信件。这项研究发现的新信息如下：第一，他被任命为印度(今印度尼西亚)、荷兰殖民地的军医，从荷兰前往巴达维亚进行调查时，他的目的地不是日本，而是巴达维亚；第二，他的叔叔约瑟夫·洛茨反对西博尔德去印度。相反，洛茨推荐西博尔德在西博尔德家族传统的医学职业上取得成功，并在家乡维尔茨堡大学担任讲师(Privat Dozent)。总而言之，西博尔德的东方研究之旅完全是基于他的个人动机，而不是得到他家人的同意在未来，我想继续破译他的私人信件，调查他的同伙圈子，他去日本的动机以及荷兰政府的意图。

The purpose of this research was to interpret and organize the documentary materials of the German doctor, Philipp Franz von Siebold, and translate them into Japanese. These materials consisted mainly of the remaining personal letters. Siebold visited Japan in 1823, and introduced modern sciences into Japan. In addition, he pioneered scientific research on Japan in the West.Among the documents concerning Siebold, housed by the Von Brandensteins (Siebold's descendants residing in Germany), are the letters addressed to Siebold and drafts of letters written by Siebold during the period of 1822-1823. These letters were pulled out, reprinted, and translated into Japanese during the three years of our research period.Siebold's letters during the period of 1822-1831 were also data-based. Combining those data, the necessary materials to determine the circle of his associate and his letters published up to now were investigated. New information found in this research are as follows :First, it was confirmed that when he was appointed as military doctor in India (present-day Indonesia), Dutch colony, and departed from the Netherlands to Batavia, he was destined not for Japan but for Batavia for his investigation.Second, Joseph Lotz, his uncle, objected to Siebold's going to India. Instead, Lotz recommended Siebold to succeed at the medical profession that was traditionally practiced in the Siebold family, and to be an instructor (Privat Dozent) in Wurzburg University in his hometown.In conclusion, Siebold's research trip to the East was solely based on his personal motive and was not with the consent of his familyIn the future, I would like to continue to decipher his personal letters and to investigate the circle of his associates, his motives for his trip to Japan and the intention of the Dutch government.
