김두봉
After graduating from Bosungkobo (Bosung College) in 1908, Kim Tu-bong worked closely with a linguistics professor from Bosungkobo named Ju Sigyeong, who was at that time beginning his work in the study of Hangul, for which his name would later be known, as he would dedicate his life to bring it about (the Korean script made by King Sae Jeong during the 15th century). He also worked as a teacher. In 1916 he spent a majority of his time working on compiling MalMooe, the first Korean dictionary.
