Sen Sōshitsu XV

is the 15th-generation Grand Master (''iemoto'') of Urasenke, which is one of the most widely known schools of Japanese tea, and served in official capacity from 1964 to 2002. In 1949, he received the Zen title Hōunsai (鵬雲斎). Following his retirement, he adopted the name Sen Genshitsu (玄室), with the honorary title Daisōshō, in order to distinguish him from his son and successor, Sen Sōshitsu XVI. For over seven decades, Dr. Sen Genshitsu has traveled across the world in order to promote the ethos of "Peacefulness through a Bowl of Tea". Provided by Wikipedia
