Wong Mou-lam (1886-1934) was from Guangdong, China. He completed the first published English translation of The Platform Sutra of the Sixth Patriarch in 1930. Mou-lam also translated The Diamond Sutra and the Sutra of Hui Neng, two of the most treasured works of Buddhist literature, the first of which is considered the oldest existing printed book in the world. A. F. Price is the translator of the ancient and revered Zen Buddhist scriptures The Diamond Sutra and the Sutra of Hui-neng. In her book Embracing Illusion: Truth and Fiction in the Dream of the Nine Clouds, author Francisca Cho praised Price's work for its "readability and faithfulness to Kumarajiva's Chinese translation." W. Y. Evans-Wentz (1878-1965) was an American author and anthropologist. Evans-Wentz was an innovator in the study of Tibetan Buddhism, whose work helped to introduce Tibetan Buddhism to Western culture. While best known for publishing an early English translation of The Tibetan Book of the Dead, he translated many other significant Tibetan texts and wrote the foreword to The Diamond Sutra and the Sutra of Hui-neng. Christmas Humphreys (1901-1983) took an interest in Buddhism at a young age and founded the Buddhist Society in London in 1924. The Buddhist Society is now the biggest and oldest Buddhist organization in Europe. In 1945, he expressed his interest in world Buddhism in his famous "Twelve Principles of Buddhism." He is the author of Buddhism: An Introduction and Guide and A Western Approach to Zen, among others.
