Katsuki Sekida (1893-1987) was by profession a high school teacher of English until his retirement in 1945. Zen, nevertheless, was his lifelong preoccupation. He began his Zen practice in 1915 and trained at Empuku-ji in Kyoto and Ryutaki-ji in Mishima, Shizuoka Prefecture. He taught at the Honolulu Zendo and Maui Zendo from 1963 to 1970 and at the London Zen Society from 1970 to 1972.
