Philippe - Jacques Potteau, 1807 - 1876

Philippe-Jacques Potteau was a long-time employee of the Museum of Natural History (Muséum d'Histoire Naturelle), in Paris, France.
During the mid-1850s, he ventured into producing microscope slides on a professional level. He appears to have specialized in thin-sections of bones and minerals (Figures 1 and 2). He displayed his preparations at the 1855 Exposition Universelle, in Paris (Figure 2). Potteau did not advertise his slide-making business in Parisian trade directories, suggesting that it was a small operation, and probably did not operate for very long. These rare slides are of unusual dimensions, are generally well-made, and would be welcome in any collection.
Potteau is best known for the photographic portraits that he took during the 1860s, many of which documented visitors from outside France. These include representatives of the Japanese government who visited Paris in 1862 and 1864 (Figures 3-5).
Figure 1.
Front and back views of a ca. 1855 microscope slide by P.-J. Potteau. It is an unusual size: 3 1/8 x 3/4 inch // 80 x 20 mm. The specimen is a longitudinal section through a human cranium.

Potteau's entry in the Official Catalogue of the 1855 Exposition Universelle. He exhibited, "Cut and polished shells and wood. Microscopic preparations of fossil wood and agates for polarization". Of note, his entry was directly above that of microscope slide-maker Hippolyte Pouilliart (1826-1895), who was son-in-law of microscopist Joseph Bourgogne (1803 – ca. 1883), and who later produced slides as one of the Bourgogne Freres and as H. Bourgogne (those celebrated slide-makers are biographied elsewhere in this series).
 
Philippe-Jacques Potteau was born during 1807 in Menen, Belgium. The date, or purpose, of his move to Paris is not known. He married Marie Jeanne Proyer on September 1, 1834.
Potteau became a naturalized citizen of France on May 30, 1848. A record of that occasion stated that he was an "employé au Muséum d'histoire naturelle". Ten days earlier, he and Marie Jeanne had entered into a financial exchange (possibly to fund his naturalization process), which gave their address as 5 Rue Guy de la Brosse. That address is the same as given for "Potteau (Ph.-J.)" in the catalogue of the 1855 Exposition Universelle (Figure 2). That address confirms that our microscopist was the same man as took the celebrated photographs shown in Figures 3-5.
As noted above, Potteau's career as a professional slide-maker probably lasted for only a very short time, possibly a year or less.
He became photographer for the Anthropology Department of the Natural History Museum in 1862. However, his famous ethnographic portraits appear to have been produced as a private enterprise. Potteau exhibited photographs in London in 1862 and 1863, and Paris in 1863.
P.-J. Potteau died on July 10, 1876.
