Thus instructed, I tried the door. It happened to be "loose," and ushered me into a long dark entry, at the farther end of which a wide flight of heavy oak stairs led to the upper rooms in the rear of the building. Among these rooms, one of the first to be reached was evidently a workshop; and here was encountered the only living being as yet visible in the spacious old mansion. Upon entering, I was met by a dignified and placid old gentleman, whose appearance was very much in keeping with the house in which he dwelt. He was quite evidently of the old school, and his pleasant voice gave me an old-school welcome. A fine broad forehead rested above a pair of the most kindly eyes that can be imagined, and belonged to a splendidly-shaped head, which was totally bald, save for a slight fringe of white hairs about either temple. The mouth was, in its expression, even more prepossessing than the eyes, and the whole bearing of the old gentleman—who had evidently reached his three-score and ten, but who, as was equally apparent, carried the warmth and vigor of youth still with him—was calculated to please and impress the least observant visitor.

The late Joseph J. Mickley comprised qualities at once more attractive and more unusual than are often met with in one person. He was distinguished throughout the world, during more than a generation, for the diligence and success of his numismatic researches, and his collection of rare coins was for a long time the most valuable in this country. As a collector of scarce books and autographs he was hardly less noted or less successful. But in Philadelphia he was most of all admired for his delightful social qualities and his extensive information on a surprising variety of topics. During forty years his house was a rendezvous for a numerous group of specialists,—not alone in his own favorite pursuits, which, indeed, were both many and diverse, but in any and every department of art or learning. Coin-hunters, autograph-dealers, historical students, philosophers, musical-instrument-makers, noted performers, and performers of less note, all the way down to "scratch-clubs," were his constant visitors for years. It is probable that no private house in Philadelphia has entertained a greater number of intellectually distinguished people than the old mansion just referred to, where Mickley resided from 1842 to 1869. Musical celebrities from every country hastened to make his acquaintance, and such was the magnetism of his personality that acquaintances thus formed seem never to have been lost sight of by either host or guest. During his European tour, which lasted from 1869 to 1872, the then venerable traveller was continually meeting friends among persons who had called upon him at various times, dating back in one case as long before as 1820. They always appeared to have known beforehand of his coming, and he always remembered them and the circumstances under which he had first met them.

The social reunions at Mickley's were informal to the last degree, and the accommodations correspondingly primitive. They usually took place in his workshop. Crazy stools or empty piano-boxes generally served for seats. The surrounding furniture comprised barrels, cases, and chests, filled to overflowing with the host's ever-increasing antiquarian treasures. If a quartette were assembled,—and many times the musical party was enlarged to a quintette or a septette,—an adjournment was necessary to a room less crowded, but equally sparse of conventional furniture.

Mr. Mickley was always happy to join in these impromptu musical assemblies, when occasion offered, although performing music was one of the few things which he never succeeded in doing well. He invariably played the viola on these occasions,—perhaps, as Schindler hints about Beethoven, because indifferent playing on the viola is not so noticeable as on other instruments. As was to have been expected from so pronounced an antiquarian, he had small sympathy for modern music. He even rebelled against the gentle innovations of Mendelssohn, contending, not without an approach to accurate judgment, that Haydn and Mozart had completely covered the field of chamber-music. While in the midst of numerous and always congenial pursuits during his long life, quartette-playing remained a favorite pastime of very many days in very many years.

Mr. Mickley's intellect was so many-sided and so evenly balanced that it is difficult to name his predominant bias. It is very nearly safe, however, to say that this was his historic faculty. In the writings, still chiefly unprinted, which were left behind him, he was at once the most minute and the most compact of historians. Emerson never condensed his rare thoughts into smaller compass, not even in his "English Traits," than Mr, Mickley has condensed his facts and observations. There is a small pamphlet extant, the manuscript of which was read by him in 1863 on the occasion of the centennial anniversary of a noted Indian massacre in Northampton County, Pennsylvania, where several of his ancestors perished. It contains historic material enough for a volume. To indicate his early passion for amassing reliable data, the same sketch shows that a portion of its facts had been obtained, while he was still a boy, from then aged eye-witnesses of the affair, nearly fifty years before its story was thus put into permanent shape.

He mastered the Swedish language, after having passed his seventieth year, chiefly that he might write a correct history of the first settlement of Swedes on the Delaware River below Philadelphia. At the age of seventy-two he spent several months in Stockholm, the capital of Sweden, and while there placed himself in communication with every prominent librarian of the country, besides scholars in Denmark, Holland, and Germany. He personally inspected a great mass of documents and ancient volumes. Yet the result of all this is contained in a manuscript of less than thirty large folio pages, literally crowded with invaluable data. This was read before the Historical Society of the State of Delaware in 1874. It has never been put in type, and is almost wholly made up of material which has no existence elsewhere in the English language.

A single instance will serve to show the minuteness and persistence of his investigations. In one of the public libraries of Stockholm Mickley discovered an ancient Dutch manuscript signed by Peter Minuit. No scholar within reach could master its contents. The private secretary of the ambassador from Holland, who was appealed to, asserted beforehand that he "could read anything that ever was written in Dutch." Yet, after a long inspection, he frankly owned his inability to decipher a single word of it. Mr. Mickley was determined to ascertain the contents. As the document could not be bought at any price, and could not even be removed over-night from its place of keeping, he caused photographs to be taken of it. One such copy was sent to a very learned acquaintance in Amsterdam, and another to a noted scholar at Leipsic. In the course of subsequent travels he found accurate translations awaiting him from both sources. The importance of the manuscript in this connection will be the more appreciated when it is remembered that Peter Minuit commanded the first expedition ever sent to the shores of the Delaware River.

Being thus by nature an historian, it is but natural that Mr. Mickley should have left behind him ample materials for telling the story of his own life. From these we learn that the family name was originally Michelet. It dates back to the French Huguenots who, after the revocation of the Edict of Nantes, settled in Zweibrcken, a Grerman province. The first foothold of the family in this country was established in that portion of Pennsylvania which has for more than a century been thickly peopled by that enlightened and art-fostering sect, the Moravians. It was from the Moravian influence that Joseph J. Mickley first experienced a fondness for music and its appropriate artistic surroundings. He was born March 24, 1799, at South Whitehall, a township then in Lehigh County, but originally comprised in Northampton. At the age of seventeen he went to Philadelphia as apprentice to a piano-maker. At that time the method of building a piano-forte was as different from the advanced art of these days as was the instrument itself. The piano-maker had then to work from the legs upward. His necessary duties demanded knowledge which is now distributed among several entirely distinct sets of artificers. That young Mickley satisfactorily completed his apprenticeship may be inferred from two facts: he started in business for himself in August, 1822, and in October, 1831, the Franklin Institute awarded him a prize for skill in the manufacture of pianos.

From this time on, his business life, though of long duration, was uneventful, and may be summed up in very few words. From his original starting-place at No. 67 North Third Street, he removed, four years later, to a store on the site now occupied by a portion of the publishing house of J.B. Lippincott Company. Here he remained until 1842, and then established himself in the building mentioned at the beginning of this article, where he continued to live until the final closing up of his business in 1869.

It does not appear that Mr. Mickley was ever actively engaged in the manufacture of piano-fortes. He continued, however, to tune pianos to the end of his life; and it is reported that he could never be induced to alter his terms from the original fee of one dollar which was customary forty years ago. He also became noted far and wide as a repairer of violins and other stringed instruments. At one time, a violin which had belonged to George Washington was sent to him for this purpose. Ole Bull, who happened to be in town at the time, hearing of the circumstance, hastened to the shop for the purpose of examining and playing upon the historic instrument. Mickley also became an authority in regard to the value and authenticity of these instruments, although he never indulged in the passion of making collections in this field. His minuteness of observation was frequently manifested. While stopping at Venice in 1870 he notes down in his diary, "A man came to the hotel with some violins for sale. Among them was a Hieronymus Amati. It was a good one, but the head and neck were not genuine." At another time, a violin was sent to his place from a distant locality for repairs. The instrument was preceded by a lengthy letter beseeching his special care for its welfare, and setting forth in extravagant terms its great intrinsic value and its peculiarly interesting "belongings." Anticipating a treasure, Mr. Mickley sent for some violin-connoisseurs to enjoy with him a first sight of the precious instrument. On opening the express-package a very worthless "fiddle" was revealed. After the laugh had gone round, he said dryly, "I think the value of this must be in its 'belongings.'"
