Over the course of thirty years, Michel Benoist served the Qianlong Emperor on a number of construction projects and as an advisor on European affairs. The Qianlong Emperor revered Benoist as a source of intellect and a window into the ideas of the European Enlightenment. According to Joanna Waley-Cohen, the Qianlong Emperor and Benoist conversed over various topics such as "Western science, philosophy, warfare, cartography, shipping, and navigational practices,” accentuating the cosmopolitan interests of the Qianlong Emperor. Many of Benoist's accomplishments have been documented by two authors: Louis Pfister (1833 - 1891), and Alphose Favier (1837 - 1905), a Catholic Bishop based in Beijing.
