Henry and William exhibited twelve microscopes at the 1863 Annual Soiree of the RMS. William does not appear to have become a member of those or any other microscopical society. Henry joined the Royal Microscopical Society in 1863, and the Quekett Microscopical Club in 1866. Crouch undertake to supply objectives of high quality for those who wish them, but we congratulate them, and other successful makers of cheap instruments, on the good they are accomplishing, as it is by such means only that the taste for microscopic studies can be extended, and students trained so as to be able to employ with advantage the exquisitely perfect instruments and glasses that our best makers can produce”. We tried a number of objects with the two-inch and one-inch powers, and can state that few students will desire a greater perfection or refinement of performance.

The prism of this instrument performs well, as do the cheap series of glasses with moderate angles of aperture. A few minutes’ practice will enable any one to work this arrangement so as to be useful with a low power, or with a quarter. If the object-holder is pushed upwards, the links are straightened, while, if it is pushed downwards, they are bent into elbow-joint angles, and lateral motion is easily effected. The lowest link is screwed to the stage a little out of the centre. The object-carrier, furnished with two spring clips, is attached to a sort of chain composed of three flat links joined to each other by screws, so as to produce a moderate stiffness of motion. Pillischer, to act as a substitute for the superior, but necessarily expensive, screw movements. The novelty consists in a moveable stage, intended, like the excellent one devised by Mr. Crouch have introduced a new binocular microscope to meet the demand for an instrument of moderate price and sufficient excellence for ordinary purposes. The Intellectual Observer published a review of the Crouch binocular in April, 1863, “ Messrs. She included a description and picture of a later version of Crouch’s binocular in her classic book, Objects for the Microscope. Clark’s testimonial was dated November, 1862, consistent with Teasdale’s later recollection. Carpenter and Louisa Lane Clark (Figure 3). Crouch now supplies but otherwise it is as perfect as a binocular could be”.Īdvertisements for the Crouches low-priced binocular microscopes include testimonials from celebrity microscopists such as William B. I have not, of course, Zentmayer’s glass rotating stage, and the other improvements Mr. I was so fortunate as to get one almost at the first, and have seen few binoculars to equal, and none to surpass it. Crouch were pre-eminently successful, and the position gained by them has been ably sustained to this day. Washington Teasdale later wrote that “ in 1862 … there was … a demand for a cheap binocular, and, in meeting this, Messrs. In particular, Crouch brought out a greatly-admired binocular microscope (Figures 2 and 3). The partners soon focused on producing good-quality, less-expensive microscopes for the middle-class microscopist and student. They evidently realized that there was a limited market for knock-off mimics of high-end microscopes. The Crouch brothers initially produced copies of the microscopes that Henry had made for Smith, Beck & Beck (Figure 1). Crouch shop was located on Regent’s Canal Dock, Commercial Road, London, and their earliest instruments bear that address (Figure 1). William does not appear to have been trained as an optical worker – the 1861 census listed him as being a “ civil engineer”. His younger brother, William, joined him. Henry left his masters and formed his own company, probably in early 1862. The 1861 census records that the 22 year-old was still in that position. Henry Crouch learned his trade as an apprentice with Smith, Beck & Beck.
But the father managed an iron works and died in 1882, whereas every aspect of Pearce Henry Crouch’s life is consistent with him being the microscope maker. His father’s name was also Henry, which has caused confusion to some historians, who have occasionally attributed the Crouch optical business to the father. Pearce Henry Crouch used his middle name professionally, and so will be referred to by that name throughout this essay.
