Description2006-1-0114c is a stage centering glass for use with a Zeiss mechanical stage, like 2006-1-0114b, which accompanied a Zeiss stand Ia laboratory monocular compound microscope (2006-1-0114a). This centering glass is presently stored in the parts box of that microscope.
The stage centering glass is a rectangular glass slide with a cross ruled on it. It also has two paper labels. The one on the right reads: "Carl Zeiss / opt. Werkstaette / Jena. / No. ...." The one on the left reads: "Der Tisch / ist centrirt, wenn / der Nonius / I auf .... / II [auf] .... / steht." The dotted lines are sometimes filled in with numbers once the centering glass is calibrated to a given mechanical stage whose serial number would be written on the right-hand label.
A small rectangular box covered with dark maroon leather and lined with black velvet holds a stage centering glass. It is signed, "KREUZTISCH- / CENTRIRGLAS" and "C. ZEISS JENA" in gold lettering.
An instruction sheet for its use is folded up on the parts box. It is entitled, "Benutzung des Strichkreuz-Objectträgers zur schnellen Centrirung des beweglichen Objecttisches." It is written in German and is dated 1896. A scan is attached to this file.

ProvenanceLydia Rabinowitsch-Kempner, Berlin, circa 1898-1935; Robert Kempner, Berlin, 1935-1949; Walter Kempner, Durham, NC, 1949-1997; gift to CHSI, 2006.
Historical AttributesThis microscope was original owned by Lydia Rabinowitsch-Kempner, an eminent bacteriologist and a research associate of Robert Koch in Berlin at his Institute for Infectious Diseases. In 1895 she went to the Women's Medical College of Pennsylvania in Philadelphia, where she was appointed the first director of the Bacteriological Laboratory. She married Dr. Walter Kempner in Berlin in 1898 while working again with Koch. She collaborated with Koch until his death in 1910. Rabinowitsch-Kempner was the first woman ever to hold the title of professor in Prussia. Her specialization was the bacteriology of tuberculosis.
When she died, the microscope stayed in her house in Germany until 1949. Her son, Robert Kempner (who was a prosecutor at the Nuremberg Trials) sent the microscope to his brother, Walter Kempner, who lived in the US in Durham, NC (he was professor of medicine at Duke University). When the latter died in 1997, the microscope was passed to an heir. It was given to CHSI in 2006.
