What it is

A typewriter that composes each Hangul syllable by combining initial, vowel and final consonant in block position. Earlier Korean typewriters were slow or impractical because they required a keyboard of hundreds of characters.

There were earlier Korean typewriter prototypes (for example Yi Won-ik's, 1914). Gong, an ophthalmologist, patented in 1949 the block-based model that proved practical; dates and priority of each prototype are debated.

What it led to

  • mechanical writing in Hangul and its three-set keyboard (sebeolsik)
  • the debate over the standard Korean keyboard (dubeolsik)
  • foundation of Hangul writing on computers
