A PRELIMINARY LISTING OF SERIAL NUMBERS FOR MICROSCOPES BY WALTER BULLOCH AND SUCCESSORS


This page is a preliminary listing of serial numbers of microscopes made by or attributed to Walter H. Bulloch and (later Emil B. Meyrowitz), last updated January, 2016. To this date, about fifty stands are listed and the serial numbers range from 77 to 675. Of the fifty stands listed, at least six appear to be assembled and modified by Meyrowitz after Bulloch died. At least four stands have dual signatures which imply these stands were simply sold by Meyrowitz as Bulloch's New York agent.

The listing here also contains corresponding information including the current location of the microscope, if known, and pictures and links, if available. It is obviously a work in progress, and I would appreciate additional entries. Anyone who contributes will get credit, or if desired, will remain anonymous. My goal is to try to create as complete a list as possible to allow for some additional research-please help if you can; send me an image or images if at all possible,  and let me know if you will allow me to post them on the site and how you wish to be credited.   if you cannot supply images, please at least let me know your model and serial number.  Contact me at: collector@microscope-antiques.com.   Some owners prefer to remain anonymous, whereas others would like something mentioned so please let me know which is you preference

Please note that the 'Model' is sometimes referred to by different names at different times. For example, it is likely that the 'Congress Jr' microscope became the later (2 pillar) version of the Professional. So in earlier years there was the Congress Jr, a two pillar stand, and the Professional, a large one-pillared microscope. A smaller one-pillared microscope later became known as the 'Professional No. 2'. Even more confusing, as is clear from both the descriptions and illustrations in the 1890 catalog, the Professional No.2 and the Biological No.2 were identical in that time period except for the longer tube length (and the support for tube) for the Professional No.2. I have personally confirmed this fact by actual examination and measurement of many of the instruments listed here, even those not im my own collection.

It should also be noted that, although the location of the serial numbers varied, not all Bulloch microscopes have serial numbers at all. This is proven by the 'New Student' Model on this site.

Note that dates of manufacture stated in the table are estimates, and as such, the dates are preceded by c. (circa). These estimates may not always be accurate, as some are extrapolations, and it has been shown in the past that makers of microscopes do not always follow a strict chronological order nor always use later serial numbers for later dates. In the case of these instruments, this seems to relate mainly to the fact that the stands sold and/or made by Meyrowitz have serial numbers that are neither in chronological order, nor correspond to Bulloch's serial numbers. This is certainly true for Bulloch/Meyrowitz numbers 112, 117, and 201-211. As examples, numbers 112 and 117 cannot possibly be from Bulloch's early production as these are both the 'Histological' model which was not in existance in the 1870's, or even the early 1880's, being first seen in the 1890 catalog. The two microscopes both numbered 201, are another interesting discrepancy in that although the signatures are slightly different, they are both signed as 'Meyrowitz Maker'. It is almost certain that these serial numbers, not chronologically related to the others, were created, or used, separately after Bulloch's death, and are Meyrowitz's numbers. The microscopes, with serial numbers 201 (second), 204 and 211, were clearly made in the 1890's, because some of their features, such as a diagonal rack and spiral pinion focusing, are not usually (if ever) found on American microscopes prior to the 1890's; furthermore, higher numbered Bulloch first-class stands have straight racks and this would not be likely if they had been made later than the ones with lower serial numbers (like 201) with diagonal racks, a feature that is more advanced.

It is the Author's opinion that these modified microscopes (112, 117 and many, (but not all) with numbers 201 through about 211, and likely others), were assembled from standard Bulloch parts, (likely in stock at the time of Bulloch's death), and that the more modern additional features were the actual scratch-constructed parts. Some of these parts such as the Kohler-condenser fittings, much more modern and generic in appearance, were not made in the same style as the rest of Bulloch's work. See for instance the knobs on my number 201 to control the Kohler-type condenser assembly.

Of these instruments, there are two with serial number 201 both Meyrowitz products, and two with serial number 205, one of which is by Meyrowitz and the other one by Bulloch himself. This proves two things. First that Meyrowitz used their own numbering system, ignoring any that Bulloch may have numbered himself, and second, that the Meyrowitz numbers cannot be equated chronologically to the others.


(?) Means this is uncertain, possibly due to image unavailability.

N/A means no satisfactory image is available, or if it is, the photographer will not allow its use on this site, or is unavailable to give permission.

Another short table reconciling all these stands is presented below.

Another web page devoted to the various signatures on Bulloch microscopes is available on this website.

A separate listing of only the stands signed by Meyrowitz, or both Bulloch and Meyrowitz is also available. By nature some of these stands were made solely by Bulloch while Meyrowitz was his New York agent. The ones that are signed 'Meyrowitz Maker' or 'Bulloch's Patent' were likely sold after Bulloch's death in 1891, and usually contain modifications of the original design.

A web page devoted to the evolution of the various Models of Bulloch microscopes is also available on this website.

77 c. 1873 'A' Model A microscope This example was sold in the 20th century by Tesseract in 1986. It was in poor condition and lacked its substage assembly. It had the important signature of 'W. H. Bulloch Maker, T.F. Nelson, Agent, Chicago'
103 c. 1878 'D' Bulloch Model D Note the 'English' or 'Crouch' type of foot, rarely if ever produced by other American microscope makers. Private Collection
104 c. 1880's-1890 'Histological' Bulloch Histo Model Signed 'Bulloch Patent, E.B. Meyrowitz, New York, Pat'd 1880'. This stand is unusual in that it has a Meyrowitz signature but straight rack and pinion which may make it earlier than the other Meyrowitz-signed stands. Private Collection
112 c. 1891 HISTOLOGICAL bulloch histological Note the single swinging tailpiece which carries both the condenser assembly and the mirror, and the flat tripod foot. It is signed: 'BULLOCH'S PATENT, E. B. Meyrowitz, MAKER, NEW YORK, PAT'D 1880' although the '1880' looks to be crudely added, and would be incorrect on any account, as there is no Bulloch patent in 1880 for a microscope, as it was in 1879. Private Collection
115 c 1880 CONGRESS Congress Microscope Note the new form of glide stage with two supporting pressure points instead of one. Private Collection
117 c 1880 NEW BIOLOGICAL (BIOLOGICAL No.1) New Biological Microscope This example has stage rotation but not a mechanical stage. The foot is signed: 'W.H> BULLOCH, CHICAGO, PAT'D 1879'
This, unlike the next No. 117, is a purely Bulloch product. This is the lowest serial number for this model I know of at the time of this writing(2017)
Private Collection
117 c. 1891 HISTOLOGICAL bulloch 117 Note that this microscope has a single swinging tailpiece which carries both the condenser assembly and the mirror, and the asymmetrical flat tripod foot. The foot is signed 'Bulloch's Patent, E.B. Meyrowitz Maker, New York, Pat'D 1879'. This example has a glass-covered glide stage ('Sliding Object Carrier'), with single pressure point, but the slide carrier is missing. The word 'maker' associated with Meyrowitz's signature implies this stand was made after Bulloch's death, about 1891, but might also simply be a Meyrowitz claim tolerated by Bulloch at the time. Private Collection; sold at Christies auction in Los Angeles in October of 2001.
121 c 1880 NEW BIOLOGICAL (LATER CALLED THE BIOLOGICAL NO. 1) Bulloch Biological Note the second version of the Bulloch Mechanical stage with concentric horizontal controls projecting from the top of the stage. This model could be supplied with either a 'Clip Stage' (plain stage with stage clips), a mechanical Stage, or 'Sliding Object Carrier' Stage; it could also be supplied with Gillett diaphragm, as well as graduated substage and mirror bars, and even as a binocular model for extra cost.

139 c 1880-182 LITHOLOGICAL (first form) first Bulloch Lithological Scope According to a review article published in the 'American Geologist' in 1889, this was the first purpose-made Petrological microscope made in the U.S.A. produced in 1880. It is nearly identical to number 138, except for the nosepiece and other fittings to allow petrographic work. -------
143 c 1880-1882 NEW BIOLOGICAL OR BIOLOGICAL NO 1. bulloch biological #143 There is no round plate between the bottom of the pillar and the top of the asymmetrical foot. The two tailpieces are zig-zag in shape. The condenser fitting is manually moved up or down. The slide holder is made of brass. Ebay Internet auction, December 2011.
144 c 1880-1882 NEW BIOLOGICAL OR BIOLOGICAL NO 1. N/A Has a horizontally oriented mechanical stage. There is no round plate under the asymmetrical foot. The two tailpieces are zig-zag in shape. The condenser fitting is manually moved up or down. Ebay Internet auction, 2004.
149 c 1880-1882 CONGRESS Bulloch 149 Note the third version of the Bulloch Mechanical stage with concentric vertical controls projecting upward from the top of the stage, allowing full stage rotation. The image is from an engraving, the actual stand is in a private collection. The signature on the actual stand is slightly different than the signature on the engraving. Private Collection
158 c 1880-1882 CONGRESS Bulloch 158 Note the third version of the Bulloch Mechanical stage with concentric vertical controls projecting upward from the top of the stage, allowing full stage rotation. It is said to be signed: 'W.H. Bulloch, Chicago, Pat'd 1879, 158' The Billings Collection
177 c 1881-1883 PROFESSIONAL (2 PILLAR) bulloch professional 177 This binocular microscope had two zig-zag shaped tailpieces, and the second version of mechanical stage. The equiaxed foot has a circular plate but without calibrations. Private Collection
186 c 1882-1883 NEW BIOLOGICAL (LATER CALLED THE BIOLOGICAL NO 1.) click here This microscope had two zig-zag shaped tailpieces, and the glide stage with a single pressure point, although the stage glass and slide holder are missing. The equiaxed foot has no circular plate at the place where the pillar meets the foot. This microscope has the signature of 'Pat'd 1879, W.H. Bulloch, Chicago, Ill' on the top surface of the foot, but the serial number of 186 is stamped on the underside of foot. This model could be supplied with a 'Clip Stage', mechanical stage, or 'Sliding Object Carrier' Stage; it could also be supplied with Gillett diaphragm, graduations to the substage and mirror bars, and even as a Binocular model for extra cost. ars machina.com collection (Collection of Tom Grill)
200 c 1882-1884 BIOLOGICAL NO. 2 N/A This microscope lacks the round plate under the pillar and has the older asymmetrical foot. It does have the newer straight double swinging tailpieces, but not the improved condenser assembly seen starting with serial number 201; this example has the older simple substage condenser assembly. Private collection
201 (earlier model) c 1891. BIOLOGICAL NO. 2 N/A This instrument has a similar but NOT identical signature to the other number 201. It is signed: 'E. B. Meyrowitz, MAKER, NEW YORK, Bulloch's Patent, 1880' with the E. B. Meyrowitz in script. The number 201 is engraved on the edge of the same toe as the signature. The number includes a 'script' type of numeral instead of a block letter type of 2, as is found on the microscope which is the next entry. Private Collection
201 (later) c 1891 BIOLOGICAL NO. 2 Bulloch Biological No. 2 Microscope Note the third version of the Bulloch Mechanical stage with concentric horizontal controls projecting from the top of the stage. Also note the improved substage, designed specifically for the Biological No. 2, and noted for the first time in the Journal of the RMS, in 1884, Vol V4, part 1, sect2,page 279. The substage was later changed by Meyrowitz who added the rack and pinion offset to the iris. This is seen on other examples of the same microscope, as in serial number 211 listed below. More interesting is the use of spiral or diagonal rack and pinion coarse focusing, a feature invented by Swift after 1890. Note that there is another microscope with the serial number 201, also with Meyrowitz signature, though the signature is slightly different. Differences include the 'script' for the older 201, vs block numbers for the later version. Also the words 'Bulloch's Patent' appear to be stamped, as opposed to actually engraved, albeit in a similar font, on the older 201. In addition, the patent date on the older example is incorrectly listed as 1880, whereas the newer example has the correct date of 1879. This Collection
204 c 1891. BIOLOGICAL NO. 2 Bulloch biological No 204 Note the nickel-plated brass gliding slide carrier and an extra knob at the top of the optical tube which clamps the drawtube in position. This instrument has the same advanced substage and also has spiral (diagonal) rack and pinions for coarse focus and the substage focus as the late 201 above. Private Collection
205(earlier model) c 1891. PROFESSIONAL Bulloch No 205, Professional Model Signed: 'W.H. Bulloch, Chicago, PAT'D 1879' This binocular microscope, made by Bulloch himself, has a serial number identical to one sold by Meyrowitz after Bulloch's death, though they are different models (see next entry). Note the second version of Bulloch's mechanical stage.
205 (newer) c 1891. ? BIOLOGICAL NO. 2 ? Bulloch No 205 Signed: 'E. B. Meyrowitz, maker, New York, Bulloch's patent 1879, no. 205' This microscope was part of Eli Buk's collection and sold at auction (lot #713) upon his death in 2013. This is one of the instruments sold by Meyrowitz after Bulloch's death and has the same serial number as the entry immediately before this one, but was sold much later.
211 c 1891 BIOLOGICAL NO. 2 For an almost identical microscope see number 201 above. This microscope is virtually identical to number 201, except the stage has been replaced by a pear-shaped platform and a Bausch & Lomb accessory stage. There is an associated eyepiece micrometer (maker unclear), and a vertical illuminator (not by Bulloch). The substage assembly, modified by 'Meyrowitz,' is exactly the same as in number 201. Another addition is a clamping lever at the trunnion joint to more securely fix the inclination at a chosen angle. Dittrick Museum of Medical History of Case-Western Reserve University(Cleveland, OH)
221 1880's; after 1880, prior to 1891. PROFESSIONAL (2 PILLAR) bulloch 221 This binocular microscope is an example of the later 2-Pillar Professional Model Private collection
248 c 1882-1884 ? BIOLOGICAL NO. 2 N/A This microscope is very incomplete, lacking part of substage and the stage. This is likely a Biological No. 2. sold at auction in July 1997
251 c 1883-1885 CONGRESS Bulloch Congress Note the THIRD version of the Bulloch mechanical stage with concentric vertically projecting controls, allowing full rotation of the stage. Golub Collection, U.C. Berkeley
260 c 1883-1885 PROFESSIONAL (2-PILLAR) click here This restored Bulloch professional features dual pillars and the second version of mechanical stage with horizontal concentric controls. Wissner Collection
262 c 1883-1885 CONGRESS Bulloch Congress Microscope Note the THIRD version of the Bulloch Mechanical stage with concentric vertically projecting concentric controls, allowing full rotation of the stage. This collection
268 c 1883-1885 HISTOLOGICAL N/A This microscope was misidentified on Ebay as a Professional. It is a Histological as it has only one swinging tailpiece with sliding fittings, not driven by rack and pinion. It had a glass surfaced glide stage with sliding carrier. The unusual signature on top of the foot includes the Patent date of 1879 in larger block letters than the signature of W.H. Bulloch Chicago. Also we note the serial number on the bottom (underside) of the foot in this microscope. Ebay Internet auction, 2008.
282 c 1883-1885 BIOLOGICAL NO. 2 Bulloch No 282 Microscope Note the SECOND version of the Bulloch Mechanical stage with concentric horizontally projecting concentric controls, limiting the rotation of the stage. This microscope has been referred to by some as a Professional No. 2, but this is actually incorrect. The only difference between the Professional No. 2 and the Biological No. 2, is the length of the limb where it meets the optical tube and the length of that tube. They are otherwise identical. The Biological No. 2 had a tube length of 5-6 inches, whereas the Professional No.2 had a tube length of 8-8.5 inches (excluding draw tube). This microscope has the shorter tube length. An unusual feature of this microscope is that the fine focus knob is much larger than the fine focus of most other Bulloch microscopes. The patent date is engraved above the signature on the foot, however the serial number is on the underside of the foot. Private Collection
NONE c 1885 'NEW STUDENT' new student microscope This microscope has the earlier zig-zag tailpiece, and was featured in an ad as well as a book of 1885. This microscope has no serial number on it at all. This Collection
301 c 1891 or later 'PROFESSIONAL' (2 PILLAR) bulloch301 This microscope has the later straight tailpieces, and the third version of mechanical stage. The equiaxed foot has a circular plate but with calibrations. This is a monocular scope. Signed: 'Bulloch Patent, E.B. Meyrowitz, New York, Pat'd 1880' This microscope also has a diagonal rack and pinion, which means it is a later model, likely made after Bulloch's death. Another distinguishing feature of this particular microscope is the lack of the angular support plate from the limb to the stage. Private Collection
308 c 1885-1888 PROFESSIONAL NO.2 (1 PILLAR) bulloch 308 This microscope has the later straight tailpieces, and the rotating glide stage. The equiaxed foot has a circular plate but without calibrations. It has the newer improved substage condenser assembly that swings out of the optical axis, and was first developed for the Biological No.2 about 1884. This is a monocular microscope. Billings Collection
327 c 1880's-1891 perhaps before 1885 HISTOLOGICAL bulloch Histological 327 Note the Brass Gliding stage with single pressure point. Slide holder width 3 inches. Private Collection
328 c. 1885-1888 CONGRESS (FINAL FORM) Congress microscope Note that the tailpieces are both flat and straight. Also note that Bulloch had now added rack and pinion adjustment to the mirror. Also note that despite its higher serial number, this instrument has straight racks and pinions. This microscope currently resides in the Brooks Collection

381 c. 1885-1888 CONGRESS (?) N/A This microscope is part of the Billings Collection, but not pictured in the catalog. It is said to be a duplicate of their much earlier Congress stand number 158, which is shown in the catalog and in this table above. This is very unlikely to be an exact duplicate because of the much later serial number. It is said to be signed: 'W.H. Bulloch, Chicago, Pat'd 1879' Billings Collection
383 c. 1889 PROFESSIONAL LITHOLOGICAL bullochproflith This is a double pillar stand with all the features of the first Bulloch Lithological No. 139 above, but with the addition of  straight tailpieces and a very complicated mechanical stage.  Interestingly it did not have rack and pinion adjustment to the mirror. The American Geologist of 1889, and in Bulloch's catalog of 1890.
392 c. 1885-1890 BIOLOGICAL NO. 2 N/A Note that the tailpieces are both flat and straight. This microscope, a monocular is equipped with a glide stage attachment, but with only a single pressure point. The new form of substage condenser assembly was provided. The foot is asymmetrical on this example. This instrument was lacking its stage plate when sold as well as he centering knobs for the substage. It has an unusual signature with the serial number and patent date stamped on the underside of the foot, whereas on the top it is engraved in curving block letters: 'W.H. Bulloch, Chicago, Ill. Ebay Internet auction, 2014.
406 c. 1885-1890 TRANSITIONAL STUDENT Bulloch Student There is only one flat and straight swinging tailpiece. Also note that the signature is on the top of the stage, and serial number is on the underside of the stage. This microscope was sold on Ebay, and the seller was kind enough to allow me to use his images here on my website; it now resides in the Brooks Collection.
412 c. 1885-1890 Professional No 2. bulloch prof no 2 scope This is a Bulloch Professional No.2 with the longer tube length, which is the only feature differentiating it from a Biological No. 2. This is example is signed 'W.H.Bulloch, Chicago' on top of the foot with the patent date and the serial number on the underside of the foot. This example has with it two stages, the mechanical stage and the gliding stage, as well as some additional accesories. The provision of both stages is also noted for an example of the earlier model known as the 'Professional' as is shown on this web site. Private collection

*These stands are signed 'Myerowitz Maker' and/or 'Bulloch('s) Patent' and the ones with diagonal rack and spiral pinion were likely made after Bulloch died in 1891. They do not relate chronologically to the others. Earlier ones sold by Meyrowitz apparently have straight rack and pinion (numbers 104, 339) but interestingly number 301 has diagonal rack and spiral pinion, further proof these numbers are not in chronological order.
