Mozi would be mine. He was a skilled artisan and engineer during the Warring States period in China who was widely sought for his services in building fortifications. He wrote texts on geometry and logic that predate Euclid's Elements, and he believed in the universal love of all mankind. During the Warring States Period, his followers went from city to city, helping fortify cities that were under attack. Their skill was such that news that a city was being aided by a Mohist was enough to convince generals not to attack.

Mozi was a badass.
