William Richards Castle, Jr.
( June 19, 1878 - October 13, 1963 )

1818 R St. NW, Dupont Circle neighborhood, DC. Now the Association of American Colleges and Universities.

An educator and diplomat, Castle was born in Honolulu when Hawaii was still a Republic. His father, William Richards Castle, Sr. was the Hawaiian minister to the United States. After studying and teaching at Harvard University, the younger Castle moved to DC during World War I to work as Director of Communications for the Red Cross. Entering into diplomatic service, Castle rose to the highest levels of the United States Department of State serving as US Ambassador to Japan in 1930 and as Under Secretary of State in Herbert Hoover's administration. Castle took a strong interest in Pacific issues, in part because of his background in Hawaii.

He was the author of four books, The Green Vase (1912), The Pillar of Sand (1914), Hawaii Past and Present (1917) and Golden Years: A Sonnet Sequence (1924)
