Robert Percival Alexander (1904-1985), was born in Japan to missionary parents. His career was spent primarily at the Defense Intelligence Agency. An accomplished author who wrote on Japanese linguistics, he was also an expert on the postal history of Japan. After visiting Easter Island in 1975, Alexander began to amass a comprehensive collection of books, articles, photographs, and other materials about the island. Dr. Charles M. Love of Western Wyoming College, a friend of Alexander, assisted in the final organization and transfer of the collection to the Smithsonian following Alexander's death in 1985.
