Regarding R. H. Blyth: Blyth's four volume Haiku became especially popular at this time [1950's] because his translations were based on the assumption that the haiku was the poetic expression of Zen. Not surprisingly, his books attracted the attention of the Beat school, most notably writers such as Allen Ginsberg, Gary Snyder and Jack Kerouac, all of whom had a prior interest in Zen. - Reginald Horace Blyth
