Soyen Shaku
Chan has become especially popular in its Japanese form. Although it is difficult to trace when the West first became aware of Chan as a distinct form of Buddhism, the visit of Soyen Shaku, a Japanese Zen monk, to Chicago during the 1893 Parliament of the World's Religions is often pointed to as an event that enhanced its profile in the Western world. It was during the late 1950s and the early 1960s that the number of Westerners pursuing a serious interest in Zen, other than the descendants of Asian immigrants, reached a significant level.
