Ten Thousand
Names
Hover the canopy
Beneath the name of the one departing, the names of those who stayed were stitched.
A maninsan, an “umbrella of ten thousand people,” was a ceremonial parasol that villagers in late Joseon presented to a magistrate who had governed well, as he left his post. Every panel of cloth was embroidered with the names of those who joined in, so names that would otherwise have vanished were kept on record.
His given name, Man Choon, begins with the same character: man, ten thousand. This page is a digital maninsan, woven from the institutions, honours and people gathered under the name of Han Man Choon.

Chun-gangThe Chun-gang Prize, since 1986
His students named a prize after their teacher’s pen name.
After his sudden death in 1984, his students and successors formed the Professor Chun-gang Han Man Choon Memorial Society and established the Chun-gang Prize in his name.
Since the first award in 1986, it has honoured researchers who publish outstanding papers in electrical and electronic engineering, with the ceremony held around his birthday, 26 June.
