Reginald Horace Blyth

Reginald Horace Blyth (1898-1964) was an English scholar of haiku and Zen whose multi-volume books introduced the themes and forms of haiku to Western audiences. He had lived in Japan since 1936 and worked with Lt. Colonel Harold G. Henderson in 1945 as the liaison between the Imperial Palace and General MacArthur's occupying forces. 

There is only one letter in the NVHA archive from Blyth to Virgilio, pictured below.
