Among legal gentlemen who were frequent guests of Dr. Wistar were William Tilghman, of Maryland, later Chief Justice of Pennsylvania, who in an interesting biographical sketch has embalmed the memory of his host; George Clymer, statesman and patriot, whose name is appended to the Declaration; and Peter Du Ponceau, who, although a Frenchman, had an ardent admiration for American institutions and the primitive simplicity that characterized the old Quaker _régime_ in Philadelphia. And that the cure of souls might not be neglected, we find here John Heckewelder, the Moravian missionary, an intimate of Wistar, and a correspondent of Du Ponceau, who later translated Heckewelder’s interesting work on Indian manners and customs into the French. Here also was John Vaughan, the Unitarian philanthropist, of whom it has been said that “he represented this city as faithfully as its own name ‘Brotherly Love.’” Did they meet and talk together, these two at the extreme poles of doctrine, the devout Moravian and the Arian whose life was consecrated to the service of his brother man? If they met, and in their discourse fell upon such subjects as engage the characters in “Paradise Lost” and the “Divina Commedia,” we may be sure that in their large mutual love for mankind they found abundant sympathy, “Nor melted in the acid waters of a creed The Christian pearl of charity.” A goodly company, among whose members there is no one more worthy to be remembered than the host, generally known as Dr. Caspar Wistar, Jr., being descended from another Caspar Wistar, who came to this country in 1717. We are informed by a German scholar and a genealogist that all the Wisters, whether _ter_ or _tar_, come from one common stock in Germany, where the name is written Wüster, and that Caspar, who came to Philadelphia in 1717, son of Hans Caspar and Anna Katerina Wüster or Wister, in having a deed of conveyance prepared was put down Wistar by the clerk. This mistake he did not take the trouble to correct, and from this first Caspar has come a line of _tars_, of which Dr. Caspar Wistar, Jr., was the most distinguished. A second son of old Hans Caspar Wister, of Hilsbach, Germany, coming over later, had his papers made out properly, according to the German orthography of the name, and thus established the Philadelphia line of _ters_. We venture to give this rather lengthy explanation in view of the fact that the spelling of Wister has been a fertile subject for discussion in the Quaker City for some years, and because it is a most reasonable one, as will be admitted by all who have studied the records of past generations. In old letters and papers of the last century it is not unusual to find a surname variously spelled in the same letter, or even on the same page. This is notably the case in the voluminous “Penn and Logan Correspondence,” where Jenings and Jennings, Ashton and Assheton, Blaithwaite and Blathwayt, used interchangeably, hopelessly confuse the reader.
