Hangul supremacy
Hangul supremacy is the belief, most widespread in Korea, that the Hangul alphabet developed by King Sejong the Great's Hall of Worthies in 1443 is the simplest, most logical, most beautiful and most scientific of the world's writing systems. In its extreme form, the belief holds that Hangul is in fact best suited for the expression of sounds in all languages.
Kim Tu-bong
After graduating from Bosungkobo (Bosung College) in 1908, Kim Tu-bong worked closely with a Linguistic 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 for 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.
