Carl Weigert
Carl Weigert (1845-1904) was a German pathologist
His contributions to bacterial and myelin sheath staining gained him international recognition in the field of pathology. Founder and editor of Fortschritte der Medizin, the first journal to be written and published in Frankfurt
Along with Robert Meyer (1864-1947) is eponymously affiliated with the Weigert-Meyer rule (1877) and Weigert’s Law in 1896
Wiegert worked and studied under Julius Cohnheim, Director of Institute of Pathology, Breslau. In 1878 Cohnheim was invited to become Chair of Pathological Anatomy at the University of Leipzig, and accepted only on the condition Weigert could accompany him. Following the death of Cohnheim in 1884, many expected Weigert to succeed him. The university however, did not offer him the position, and many now speculate this was ‘largely the result of him being a Jew, and to lesser extent his lack of aggression‘. Distraught, Weigert left to take up a position in Frankfurt.

Medical Eponyms
Weigert-Meyer rule (1877)
When complete ureter duplication is present the ureter which emanates from the superior aspect of the kidney, inserts more inferomedially into the bladder. This is referred to as the ectopic orifice. The other ureter, emanating from the inferior aspect of the kidney, inserts into the bladder more laterally and chephaloid (orthoptic). This ureter is more in keeping with normal ureteric insertion.
Weigert’s law (1896)
The loss or destruction of tissue results in compensatory replacement and overproduction of new tissue during the process of regeneration or repair (or both), as in the formation of callus when a fractured bone heals.
