Why doesn't some patient drudge of a privat dozent compile a dictionary of the stable-names of the great? All show dogs and race horses, as everyone knows, have stable-names. On the list of entries a fast mare may appear as Czarina Ogla Fedorovna, but in the stable she is not that at all, nor even Czarina or Olga, but maybe Lil or Jennie. And a prize bulldog, Champion Zoroaster or Charlemagne XI. on the bench, may be plain Jack or Ponto en famille. So with celebrities of the genus homo. Huxley's official style and appellation was "The Right Hon. Thomas Henry Huxley, P. C., M. D., Ph. D., LL. D., D. C. L., D. Sc., F. R. S.," and his biographer tells us that he delighted in its rolling grandeur—but to his wife he was always Hal. Shakespeare, to his fellows of his Bankside, was Will, and perhaps Willie to Ann Hathaway. The Kaiser is another Willie: the late Czar so addressed him in their famous exchange of telegrams. The Czar himself was Nicky in those days, and no doubt remains Nicky to his intimates today. Edgar Allan Poe was always Eddie to his wife, and Mark Twain was always Youth to his. P. T. Barnum's stable-name was Taylor, his middle name; Charles Lamb's was Guy; Nietzsche's was Fritz; Whistler's was Jimmie; the late King Edward's was Bertie; Grover Cleveland's was Steve; J. Pierpont Morgan's was Jack; Dr. Wilson's is Tom.

Some given names are surrounded by a whole flotilla of stable-names. Henry, for example, is softened variously into Harry, Hen, Hank, Hal, Henny, Enery, On'ry and Heinie. Which did Ann Boleyn use when she cooed into the suspicious ear of Henry VIII.? To which did Henrik Ibsen answer at the domestic hearth? It is difficult to imagine his wife calling him Henrik: the name is harsh, clumsy, razor-edged. But did she make it Hen or Rik, or neither? What was Bismarck to the Fürstin, and to the mother he so vastly feared? Ottchen? Somehow it seems impossible. What was Grant to his wife? Surely not Ulysses! And Wolfgang Amadeus Mozart? And Rutherford B. Hayes? Was Robert Browning ever Bob? Was John Wesley ever Jack? Was Emmanuel Swendenborg ever Manny? Was Tadeusz Kosciusko ever Teddy?

A fair field of inquiry invites. Let some laborious assistant professor explore and chart it. There will be more of human nature in his report than in all the novels ever written.
