The German optician Paul Waechter (1846-1893) originally trained in the workshop of Carl Zeiss in Jena. By 1872, he started his own business in Berlin. Over the years, he produced a variety of different microscope models, but was primarily known for microscopes designed to detect the Trichinella spiralis in meat samples.

The following was extracted from the catalog of the Henry Heil Chemical Co., St. Louis, 1891:

No. 23.—Large Microscope, for bacteriological work, suitable for almost all requirements, with joint for inclination, coarse adjustment by rack and pinion, fine adjustment by means of a most perfectly working micrometer screw with divided head,  Draw-tube with mm. scale. Abbe Condenser with Iris Diaphragm,  rack and pinion for raising and lowering the entire apparatus;  the condenser system can easily be taken out and the Cylinder Diaphragm can be used in its place. Nose-piece for three Objectives. Eye-piece Micrometer, length of scale 5 mm.= 50 divisions. Objectives No. 3 and 7, Homogeneous Immersion 1/12 and 1/16.  Eye-pieces No. 1, 2, and 4 (or No. 2, 3 and 5, as desired). Magnifying Power, 49 to 1687 diameters. $ 381

No. 24.—Same as No. 23. Objectives No. 3 and 7, Homogeneous Immersion 1/12, Eye-pieces No. 1, 2 and 4 (or No. 2, 3 and 5,  as desired). Magnifying Power 49 to 1270 diameters 268

No. 25.—Same as No 23. Objectives No. 3 and 7, Homogeneous Immersion 1/12. Eye-pieces No. 1 and 3 (or No. 2 and 4, as desired).  Magnifying Power 49 to 955 diameters 247


This was the microscope of Dr. Julius Townsend Rose, MD (1869-1950). It was purchased for this collection from his grandson. On the basis of the advertisement shown above, this is the large model No. 1b, designed for bacteriological studies. Dr. Rose obtained his medical degree from Columbia University in New York in 1892 and one can therefore assume that this is the instrument he used for his medical studies and in his subsequent practice in Brooklyn NY. The following quote was extracted from a genealogy of the Rose family:

"Julius Townsend Rose, b. 28 Apr 1869, Stephentown, NY and died 23 Jan 1950 in Sonoma, California. He married (1) Bertha A Brimmer in 1893 Stephentown, NY. She was born 1869, the daughter of Henson (?) M and Augusta Brimmer. He married (2) Mabel Collins. She was born 04 Feb 1892 in New Jersey and died 17 Jun 1949 in Sonoma, California. In the 1900 census Julius states he was a teacher, and was living with his in-laws (the Brimmer’s) in Stephentown. In 1910 Julius, Bertha and Augusta are living in Brooklyn, NY where he is listed as a physician, general practioner. There is a family story that he removed his niece’s appendix on the kitchen table when he was visiting his brother Arthur".
