Keynes was an excellent writer. Some of his best writing is in his biographical sketches and essays. Keynes devoted a lot of his time and effort on biographical writings, both as an author and as editor of the Economic Journal. In this paper Keynes as a writer and editor of biographical sketches and essays is discussed and analyzed. Some of Keynes’s contemporaries thought biography was really his métier. Certain notable qualities of Keynes as a biographer that have been mentioned are discussed. Why Keynes wrote Essays in Biography is analyzed and compared with his motivation for writing Essays in Persuasion. Keynes’s writing of Essays in Biography is discussed, and new information about this presented. In the preface to the French edition of the General Theory Keynes wrote, “it fell to my duty, when I first became a youthful editor of the Economic Journal to write the obituaries of many of [the school of French Liberal economists] – Levasseur, Molinari, Leroy-Beaulieu…” It appears Keynes may actually have only written one of these.In his review of Volume X of the Collected Writings of John Maynard Keynes, Essays in Biography, Robbins writes that it contains “the entire corpus of Keynes’s biographical writings.” Volume X does not contain the entire corpus of Keynes’s biographical writings. There are at least four additional essays in biography by Keynes that are not published in his Collected Writings, and there may be many more. In the paper thirteen obituaries in the Economic Journal during Keynes’s editorship, which do not have an author listed, are discussed. Based on the style of the obituaries it is argued that Keynes wrote most of them. Keynes may have actually written as many as twelve of them. Finally, there are over thirty announcements of the death, mostly of economists, in the Economic Journal during Keynes’s tenure as editor, many of which, if not all, may also have been written by him.
