Our knowledge of Fox and of Bay is derived largely from the Additions to Thomas's History of Printing, a body of tradition of uneven reliability transmitted to Isaiah Thomas by William McCulloch, a Philadelphia printer active in the early years of the century. Selections from the six communications of the period 1812-1814 in which this information was transmitted were incorporated by Thomas in the revision of his book upon which was based the second edition brought out by the American Antiquarian Society in 1874. Long afterward the series of letters was published as a whole in the Proceedings of the Society for April 1921 under the title, William McCulloch's Additions to Thomas's History of Printing.

In these letters to Isaiah Thomas, McCulloch was recording his own memories and the accepted Philadelphia tradition. Because he was well advanced in years at the time of writing, one is not surprised to find that now and then he trips over the barrier that separates documented fact from hearsay and personal recollection. It is much to our comfort in the present instance, however, to learn that he possessed and made use of unusual opportunities to obtain correct information as to the craftsmen who are the subject of our interest. These facts which he records of Justus Fox, for example, he obtained from Emmanuel, the son and partner in type founding of that artisan, and in Justus Fox, a German Printer of the Eighteenth Century, Dr. Charles L. Nichols accepts his testimony as of general reliability. He was indebted to various relatives of Bay, among them a sister, "a plump lady of 68," for the account of him which is found in the pages of the Additions. It is possible to compare various items in McCulloch's sketches of these men with records unknown to him, but available to us, with results so little at variance that one is inclined to accord a high degree of credence to all that he wrote concerning their activities.

At the time of Sower's importation of German equipment, McCulloch informed Isaiah Thomas, he had among his journeymen an ingenious general mechanic, Justus Fox, whom he charged with the responsibility for casting the letters to be used in the great Bible. In April 1772 he employed a newly arrived Swiss silk weaver, Jacob Bay,[11] to assist Fox. Two years later Bay left Sower's service and set up a foundry on his own account in a near-by house in Germantown. Fox remained in Sower's establishment, presumably engaged in casting the large quantity of type required to keep standing an edition of the Bible. In addition to this routine work he is said to have cut and cast an unspecified amount of Roman letter before 1774, the year of Bay's separation from the Sower establishment. Working in his separate foundry, it is recorded by our volunteer historian, Bay "cast a number of fonts, cutting all the punches, and making all the apparatus pertaining thereto, himself, for Roman Bourgeois, Long Primer, etc."

That this reported activity in type casting in Germantown about the year 1774 was not a play of the imagination on the part of its historian is made certain by the definite statement that occurs in one of the non-importation resolutions of the Pennsylvania Convention. On 23 January 1775 the Convention "Resolved unanimously, That as printing types are now made to a considerable degree of perfection by an ingenious artist in Germantown; it is recommended to the printers to use such types in preference to any which may be hereafter imported."[12] Referring somewhat vaguely to this resolution, both as to content and as to origin, McCulloch tells us that even at the time of its passage Fox and Bay each claimed the honor implied in its terms. To this day the identity of the "ingenious artist" remains uncertain.

It is not clear by what evidence it was known to the Convention that "a considerable degree of perfection" had been attained in the making of type in Germantown. The only known specimen of printing type cast at that place before the meeting of the Convention in January 1775 is the German letter employed in Sower's periodical, Ein Geistliches Magazien, and it is not likely that this or any other specimen of German type would have led the Convention to a recommendation as sweeping as that which has been quoted from its journal. It could only have been a Roman letter that the delegates had in mind for a usage so general as was indicated in their resolution, and we must remain in doubt as to what specimen or specimens they had seen of locally cast type in this character. It is certain, however, that at the time of their action a font of Roman letter had been completed, or at any rate, that it was then in the process of casting. It is quite possible that a trial specimen of this font had been submitted to the Convention for its examination and approval.

It is a satisfaction to be able to introduce the new font through the medium of a contemporary reference to its use. We are indebted to the correspondence and to the diary of the Rev. Ezra Stiles of Newport, later President of Yale College, for some important information on early American type founding. Excited by Buell's efforts to make type in the year 1769, his interest in the manufacture seems to have remained in being, for on 9 May 1775 he appended the following comment to an entry in his Diary: "Extracted from the Pennsylva Mercury, whose first No was pub. the 7th of April last: printed with types of American Manufacture. The first Work with Amer. Types: tho' Types were made at N. Haven years ago."[13] The fact that Ezra Stiles was one of the earliest patrons of Abel Buell's venture in letter casting, supported as this fact is by his interest in American manufactures generally, lends a certain amount of weight to any observation that he might make on the subject of American type founding, although it is probable that he was ignorant of Sower's partial achievement of the art, just as Sower some years earlier in his claim to priority had seemed to be unaware of Buell's technically successful effort. If we may interpret Dr. Stiles's words as meaning that Story & Humphreys's Pennsylvania Mercury[14] of 7 April 1775, Vol. I, No. I, was the first published work printed in Roman letter which had been cut and cast in English America, we may unhesitatingly repeat his description of it as "The first Work with Amer. Types."

The Philadelphia newspaper which has been referred to is one of the rarest of American journals of the period. Complete files, comprising issues from 7 April to 27 December 1775, are found only in the Library of Congress and in the Harvard College Library. From the first page of its first issue, the publisher's announcement is here reproduced.

A glance at the pages of the newspaper in which the new Roman letter was first used makes us feel that in his commendable willingness to admit imperfection the publisher paid small tribute to the skill of his "ingenious artist." The letters of "rustic manufacture" were far from perfect, it is true, and in later issues of the newspaper it is observable that they had not worn especially well, but nonetheless they composed agreeably and they were sufficiently well executed to entitle them to something more than the half apology with which they were offered to the public. Their interest, however, as the first American-made Roman type to be used in a publication intended for circulation transcends considerations of worth and appearance.
