MICROSCOPE SIGNATURES BY WALTER BULLOCH, HIS AGENTS, AND HIS SUCCESSORS

The signatures on the microscopes of Walter Bulloch, his agents, and successors have varying styles and locations. These signatures also vary in size. This page is a summary of the known variations and may not even now be complete. Images have been redrawn from actual examples for clarity. I have not included examples for which there is no photograph (i.e. only an engraving), as these may reflect some 'artistic license' of the engraver and not be accurate. Note that some decorative details may or may not be present on all examples; these decorative details are shown in yellow. For actual images of most of these, listed by serial number please see the Bulloch Signature Listing by Serial Number Page, although you can also click on the images on this page to go to an example of the actual signature, if available.

Please note that in most cases I could only approximate the fonts, but did try to come as close as possible

Bullock 77 sig

EARLIEST

The earliest documented signature that I know of is that on the foot of an 'A' Stand, numbered 77. It reflects T.F. Nelson as Bulloch's agent for Chicago, a relationship that apparently did not continue, Nelson declaring bankruptcy.

Bullock 103 sig

BEFORE 1880

The second oldest signature that I am aware of is on the main optical tube of a 'D' Stand numbered 103. Again only one example like this is known to me. Note the serial number is part of the signature, a feature that will return in a different style in some later Bulloch microscopes.

Bullock Signature on No 115

BEFORE 1880

The earliest congress stand I am aware of has this signature on the foot and numbered 115. Note there is no patent date on this instrument, so this signature likely predates 1880. Again only one example exactly like this I know of. The serial number was on the angled distal end of the same toe as the signature, much like many examples that followed. Note the change in font from the prior tube signature.

Bulloch 121 Signature149

NOs. 121 to 177
AFTER 1879

This general form of signature, with minimal modifications of the decorations between the words, is found on a Biological No. 1 and also on two examples of the first Single-pillar version of the Professional model, as well as an example of the Congress model. Serial numbers range from at least 121 to at least 177. It is the first to include the 1879 patent date and implies that all stands made by Bulloch, which have serial numbers of 121 or higher, date to after 1879. The signature on number 149, includes most of the the same features, but is slightly different as shown to the right. Number 153, a single-pillar Professional has the same signature as number 149 but with slightly different decorations and the abbreviation 'PATD' is all capital letters.

Bulloch Meyrowitz Signature

NOs. 104, and?
AFTER 1891

Potentially confusing are the signatures by E.B. Meyrowitz. Early on, Meyrowitz became agent for Bulloch in New York. Later, after Bulloch died, Meyrowitz took over the business and constructed microscopes after Bulloch with modifications. It is clear that these were assembled from original Bulloch parts with changes and additions by Meyrowitz. This signature, found on number 104, uses the term 'Bulloch's Patent' and then goes on to quote the incorrect patent date of 1880. Note that this signature does not use the term 'Maker' in regard to Bulloch so it is feasible that some of these microscopes might have been produced while Bulloch was still alive. This microscope has a straight rack and pinion as opposed to the Meyrowitz spiral types. The Bulloch Student model in this collection has dual signatures (both Bulloch and Meyrowitz), straight rack and pinion, and no serial number. See the next entry for presumably later signatures with Meyrowitz claiming to be the 'Maker'.

Bulloch Meyrowitz Signature

NOs. 112, 117, 201, 201(2nd), to 211 (?)
AFTER 1891

Stands which Meyrowitz made (mostly with parts from Bulloch's stock), apparently have their own run of serial numbers. These should not be confused with those sold by Meyrowitz while Bulloch was still alive (e.g. those with dual signatures, and possibly number 104). Meyrowitz was Bulloch's agent for New York and vicinity long before Bulloch died (in November of 1891). From close study of these stands it appears to the author that the notation indicating Meyrowitz as the maker was not used while Bulloch was alive, as all so labelled have more modern features than those made solely by Bulloch. The other (earlier) microscopes have both Bulloch and Meyrowitz signatures, but do not show Meyrowitz as the maker and there is one (number 104) which uses 'Bulloch's Patent' but does not use the 'Maker'. It should be noted that the word 'MAKER' and the words 'BULLOCH'S PATENT 1879' are stamped rather than engraved, and as such, the spacing between Meyrowitz's name and these other parts of the signature vary from microscope to microscope.

Bulloch Meyrowitz Signature

NOs. 301, AND ?
AFTER 1891

This is another variation on the New York Meyrowitz Maker signature. Note the words 'New York' and 'Maker' are in reverse order from the prior, and the words 'Bulloch's' and 'Patent' are on separate lines. In addition, the script signature of Meyrowitz has a slightly greater degree of embellishment. Note also the error in the patent date of 1880 instead of correct 1879. This error was made on several other examples.

Bulloch 251 Signature

NOs. 178 to 251
AFTER 1879

This signature is similar to the next, except for the arrangements of the letters and the decorations. The biggest difference is in the word used for the abbreviation of the word 'patented.' In this example the abbreviation is 'PAT'D.' In the next example, it is simply 'PAT.' Later it returned to a similar but not identical 'PATD.' Also note that in this one the 'C' of Chicago partly surrounds the next letter h, whereas this was changed in the next example.

Bulloch 260-62 Signature

NOs. 260 to 262
AFTER 1879

This signature is similar to the last, except for the arrangements of the letters and the decorations. The biggest difference is in the word used for the abbreviation of the word 'patented.' In this example the word is 'PAT.' In the prior example, it is 'PAT'D.' Also note now the C is separated from the next letter of the word Chicago, and has two differences; a tiny loop decoration at its top end and a tiny bulge to its left in the center of the 'C'. This signature is found on a 2-pillar Professional (number 260 in the Wisner Collection) and also number 262, the Congress stand in this collection.

Bulloch 328 Signature

NO. 328 and ?
AFTER 1879

This signature, very similar to the preceding differs in the abbreviation for patented, adding 'D to PAT, and the deletion of the little dimple on the outside edge of the middle of the letter 'C' in Chicago.

Bulloch 268-82 Signature

NOs. 268 to 282
AFTER 1879

This signature seems to change the emphasis from Bulloch's name to the patent date. The spacing and location on the toe vary a bit as is evidenced by the differences on number 268 vs number 282.

Bulloch Student microscope Signature

c. 1885

The signatures on the 'New Student' model are found only on the arm, one for Bulloch on the right side and one for Meyrowitz Brothers on the other. I know of no other example and we know this model was made about 1885.

Bulloch Microscope Signature on no 392serial number under foot

NOs. 392 to 412
AFTER 1879

This signature, which seems to appear starting in the second half of the known range of serial numbers, leaves the patent date out completely. As can be seen in the image to the right, the patent date and serial number on some (but not all) of these instruments are found on the bottom of the foot. In the cases of where the signature is on the top of the stage, rather than on the foot, the serial number (without the patent date) is often found on the underside of the stage.

Bulloch Microscope Signature on no 513

NO. 513 and ???
AFTER 1879

This signature is similar to the prior except now the serial number is in the center of the Bulloch logo. On the stage the Bulloch signature appears above and the Meyrowitz signature below the hole on the stage. No patent date is quoted on this, the only example with this signature I have images of.

sig on 567

NO. 567 and ???
AFTER 1879

This signature is the same as the Bulloch portion of the one above, except that there is no accompanying Meyrowitz signature. Presumably this signature was from a similar time period, but for microscopes sold by Bulloch himself.

Bulloch Microscope Signature on no 675

NO. 675 and ???
LIKELY 1890-91

This signature, found on the stand with the highest known serial number to our present date, has no patent date in the top of the foot. This may have to do with the tendency of 'old' patent dates to lead people into thinking that the stand is not the most modern available. I even have one stand (a Professional) where the patent date was deliberately removed. It is unknown when Bulloch started to leave out the patent date on the top or even if this was deliberate.
