A biography it is not. As he remarks frequently, Mr. Kelen was television director at the U.N. while Dag Hammarskjold was Secretary General, and this is a scrapbook of curriculum vitae, anecdotes, impressions and quotations. Although ""Little Boy Dag"" appears near the beginning, and his funeral, interment and commemoration fill a chapter near the close, the intervening text is not a consecutive account of his life or even of his activities at the U.N. although a few of these (the negotiations with Peking for the release of American flyers, the Congo crisis) are roughed in. Examined more closely are Hammarskjold's sponsorship of the Mediation Room and his response to Khruschev's personal attack. Certainly he was a very private individual and hard to draw out but the Charlie May Simon biography (1967, 286, J-108), particularly, is both fuller and more searching.
