The history of the autoharp and other chord zithers is replete with innovations that were patented in one country and appeared shortly afterward in a patent issued in another country. When the dates are close enough, it can be difficult to determine who should be credited with the actual invention. Similarities do sometimes appear to be coincidental but plagiarism was common enough. One way of disguising it was to “extend” an earlier patent for a similar device to include the co-opted later innovation. Since the date of such revision was also recorded, this only partially obscured the actual priority.
Another technique was to label an instrument with the number or date of a patent that didn’t actually cover the design detail it was alleged to protect. One example of this that readers of the autoharp facet of this blog will already be familiar with, is Charles Zimmermann unilaterally repurposing the date of a US patent issued to him on 9 May 1882 for what in retrospect might be termed a proto-autoharp.

The following image is the banner of a full-page advertisement placed in the 1 May 1891 issue of the German trade periodical Zeitschrift für Instrumentenbau (Journal for Instrument Making) by the firm of zither makers Müller & Thierfeld.
with practical tuning device
The tuning device is a small fretboard placed under one string enabling the others to be tuned to it.
Müller & Thierfeld acquired legal protection for it via the Design Registry in Greiz, for a “Scale for tuning the chord zither” (Accordzither). It was registered on 14 May 1891 as a “Design for plastic products.” This protection was weaker than that of a patent and extended for three years. Other makers were producing comparable devices before it expired and it was irrelevant outside Germany in any case.

On 20 April 1893, Fredrick Menzenhauer, filed a US patent application for a “Guitar-Zither,” issued as USP No. 520651 on 29 May 1894. Its illustrations come very close to the current form of what is commonly termed a “chord zither.” The only differences are the fretted tuning device in the middle of the soundboard underneath the first melody string, and the separation between the bass string and the other strings in each of the chords (which are also recessed into the lower bridge).
Chord zithers in the form shown two images below (minus the tuning scale) are still being manufactured and Menzenhauer is generally credited with their invention. However, his patent sought protection for “certain new and useful Improvements in Guitar-Zithers” and he refers to the instrument as “my improved guitar-zither.” This implies the prior existence of some other instrument that he referred to by the same name.

The German musical instrument manufacturer, Theodor Meinhold (1846–1913), played a significant role in the popularization of the autoharp in Europe. One of his contributions was a form of sheet music that is positioned underneath the strings (adapting a scheme presented in an a US patent issued shortly before his own German patent). It graphically maps the movement of the right hand from string to string when playing a melody and numerically indicates the chord bars to be held down by the left hand for accompaniment.
Meinhold obtained German Imperial Patent No. 63702 for it in October 1891, illustrating the device schematically to permit its use with “zithers of the most differing constructions.” It includes a mechanism “for sounding accompaniment chords [through which] the playing of certain melodies is extraordinarily eased.” This accompaniment device is seen under the word “Bass” in the following illustration and was co-opted from another US patent that presented a simplified alternative to the chord bars on an autoharp. (I’ll discuss the two earlier documents in a separate post.)

The inaugural post on this blog appeared five years ago today, and has since been joined by over 130 more. I managed to prepare them with near fortnightly regularity until six months ago, when the preceding post went online. The one initially intended to follow it has yet to be finished and deals with a German gauge system for wire knitting needles.
One of the source documents consulted during its preparation reminded me about the relationship between the drawing of wire for such implements and for musical instruments. Music wire was a central concern in an earlier phase of my museum-based research and the pending post turned my attention back to it. That is also where the blogonym stringbed originated; a term used to designate the planar array of strings on an instrument such as a piano or zither. This all triggered an interest in once again writing about topics more closely related to its literal sense.

I am pleased to announce the publication of my article, “Knotting and Tatting: The Dual Role of the Shuttle as a Fashion Accessory and Instrument of Decoration,” in the Early Summer 2021 issue of The Journal of Dress History.
It is a totally reworked and expanded successor to a preliminary report on Early Tatting Instructions that was previously available via this blog but was taken offline quite a while ago. Here is the abstract of the new article:

One of the nice parts about using a blog to present the results of ongoing historical research, is the ease with which a report of “the earliest evidence [of whatever] that has yet come to light” can be amended when even older evidence is uncovered. Since such work constantly strives to extend the resulting timeline, every new success paradoxically risks invalidating a previous one. The corresponding revision of the broader narrative may entail nothing more than noting that something is a few years older than previously believed. However, things such as the radiocarbon dating of a questioned fragment of fabric can necessitate a fundamental re-contextualization of previous documentation. This in turn can effect a major change in our understanding of, say, the origin of a given mode of looped fabric production.
I tacitly tweak posts on this blog to reflect subsequent insight without calling attention to such revision. However, there have been a few stop-press situations where the retroactive editing has been paired with a new post about the details of the more recently uncovered material. The last such case (reported here) arose from my having overlooked the first attested mention of Tunisian crochet — in a Swedish publication that I had in fact examined. It appeared one year earlier than the German source I had cited.

The preceding post examined two medieval German portrayals of Mary making a garment for the child Jesus. They are apparently based on the description of the robe he wore on the Crucifix in the Gospel of John, which German exegetic texts contemporaneous with the images state that he had worn all his life. The appearance of the garment is effectively identical in both depictions but they illustrate two significantly different production techniques. One is looped in a manner that would credibly have been familiar to Mary but the other is knitted — a craft of which there is no tangible evidence until a few centuries after her lifetime.
There is nothing surprising about a text written toward the end of the first century CE describing looped fabric in a region where the first evidence of it has been dated to ca. 6500 BCE. An array of such material has also been recovered in Roman Egypt. Nonetheless, the Nile Valley or some nearby area is where the oldest known true knitting emerged and was subsequently conveyed into Europe.

There are several challenges in assessing iconographic evidence of utilitarian implements and the contexts of their use. One is recognizing the difference between a representation of an object or process that may be stylized but can otherwise be corroborated, and an imagined depiction that coincidentally appears to be plausible. This difficulty is compounded when an image includes details that can be identified with a fair degree of confidence, in proximity to others that are more likely to be misrepresented. There is also a contextual aspect to this. If graphic evidence of a tool used for handicraft appears in seemingly realistic detail at a completely unexpected time or place, particular care is needed before basing revolutionary conclusions on it.
A range of such considerations attaches to early illustrations of the production of looped fabric. Current reviews of the history of knitting are commonly illustrated with portraits of so-called Knitting Madonnas. Perhaps the best known, and certainly the most clearly detailed, is in a scene on the Buxtehude Altar painted by Master Bertram ca. 1400. It unequivocally depicts four double-pointed knitting needles used for working a garment with what is now termed a seamless yoke construction.

This post is an updated replacement for an earlier one titled Scottish and shepherd’s knitting revisited that I took offline before preparing an article on the underlying topic for publication. New questions about shepherd’s knitting and its relationship to crochet have arisen in the interim and a book that was central to the initial post sheds quite a bit of light on them. It was published in Dublin in 1835, with the title page:
