Cai Yong

Cai Yong is one of those figures from ancient history who makes you stop and think — how did one person fit so much into a single life? Active during the Eastern Han dynasty in the second century, he was a calligrapher, musician, mathematician, astronomer, historian, and politician all at once, at a time when those disciplines were barely separated. His calligraphy was so respected that the stone classics he helped inscribe outside the Imperial Academy drew crowds of scholars copying his work. He also invented the guqin style known as Jiao Wei, according to tradition, and his musicological writings survived long enough to influence later generations. What really gets me is that his daughter Cai Yan — also known as Cai Wenji — became one of the most celebrated poets in Chinese history, which tells you something about the household he ran. He died tragically in 192 CE, imprisoned under Dong Zhuo's warlord regime, mourned by students who admired him deeply. A genuine Renaissance man, two centuries before Europe invented the concept.
