徐光启
Xu Guangqi was a Chinese scholar-bureaucrat, Catholic convert, agricultural scientist, astronomer, and mathematician. He holds the title of Servant of God, and received his beatification in April 2011. He contributed to the translation of the first parts of Euclid's "Elements" into Chinese. He also worked on the reform of the Chinese calendar, which constituted the first major collaboration between scientists from Europe and from the Far East, though it was completed after his death.
