岡倉天心
In 1904 and 1905 Japanese diplomats visited Greenacre – Yokoyama Taikan, Okakura Kakuzō and Kentok Hori, signing Farmer's autograph book with quotations and drawings for a special tea service and presentations. As an institution Greenacre developed a brief set of "branch" associations including one in Washington D.C. in 1905 that began to host peace conferences.
