As far as I know, the author of Journey to the West is the Ming Dynasty novelist Wu Chengen. Wu Chengen (1500 - 1582) was a Chinese novelist of the Ming Dynasty. He wrote the monumental work, Journey to the West. Journey to the West was based on the story of Xuanzang, a monk of the Tang Dynasty, who went west to seek scriptures. It described the journey of Sun Wukong, Zhu Bajie, and Monk Sand to protect Tang Sanzang. This novel was hailed as a classic in the history of Chinese literature and an important part of Chinese culture. Wu Chengen's detailed information could be found on Baidu Encyclopedia or related institutions.
