This calligraphy is one of the autographs left by An Jung-geun (1879-1910). An Jung-geun was born in 1879, in Haeju, Hwanghae-do. In 1894, when he was sixteen years of age, he joined his father who set out to crush the Donghak rebel army, leading Sanpogun, on the request of the Province governor. In 1906, he founded Samheung School and also took over an existing school (Donui hakgyo), devoting much of his time to managing these schools. Later when he entered into armed struggle against the occupying Japanese, An Jung-geun launched attacks on Japanese reconnaissance squadrons. On October 26, 1909 when the train carrying Ito Hirobumi arrived at the Harbin Station, An Jung-geun shot him three times, as he was walking away from a group of Russian army officials he just finished inspecting, killing him. An Jung-geun was incarcerated in Lushun Prison and executed on March 26, 1910. This eight-character calligraphy that reads “Gukgaanwi nosimchosa [‘Tormented by worries about my country’]” is written in semicursive script. Along the left edge, at the top is written “Jeungangang geumchalgwan [For Prosecutor Yasuoka].” Along the right edge, at the bottom is written “Gyeongsulsamwol Yeosunokjung Daehangugin An Jung-geun geunbae [Korean national An Jung-geun, third month of Gyeongsul Year, Lushun Prison’], followed by an ink-printed palm mark. This item is 38.2㎝ by 149㎝. As the dedication states, this calligraphy was written for Yasuoka Seishi, the prosecutor of Lushun who questioned him during his stay in prison. Shortly before his death, Yasuoka Seishi gave it to his eldest daughter who later donated it to the An Jung-geun Commemoration Society (An Jung-geun uisa sungmohoe) in Korea, on February 11, 1976. This autograph is of high significance for the understanding of An Jung-geun’s life and the history of the Korean independence movement.
