The Reverend Dr. William Henry Dallinger, F.R.S. (1839-1909), parson-naturalist and microscopist, was an enthusiastic user of the Powell & Lealand No 1 microscope, and the 1891 and 1901 editions of Carpenter’s The Microscope and its Revelations, edited by him, include four engraved plates depicting the No 1 stand in use for different methods of observation. The painting of Dallinger in the Wellcome collection by Edgar Herbert Thomas, shown above, depicts him in academic gown seated at a binocular Powell & Lealand No 1 microscope. Note the similarity to the P& L No. 1 microscope pictured and discussed further by Dr Jurriaan de Groot on this website. Dallinger also used a special stand, allowing the microscope to be used vertically for fluid mounts. He conducted research into saprophytic organisms, and with the extensive signs of use on the fine adjustment, and on one of the live boxes, it is tempting to speculate that he may have been the original owner of this very microscope, particularly considering the striking resemblance to the stand here discussed. Dallinger, being an author of books about the microscope, would be a good candidate to want to have all the various P & L objectives to write about in his book. Definitive proof to support this hypothesis is lacking, however.
