Franz Volhard

As a student his instructors included Eduard Friedrich Wilhelm Pflüger (1829–1910), Bernhard Naunyn (1839–1925), Oswald Schmiedeberg (1838–1921), and Joseph von Mering (1849–1908).

He is especially remembered for his collaborative work with pathologist Karl Theodor Fahr (1877–1945) in Mannheim, where the two men carried out research of kidney diseases.

The two physicians created a classification system of renal disorders, making the differentiation between degenerative (nephroses), inflammatory (nephritides) and arteriosclerotic (scleroses) diseases.

[1] With Fahr, he published a classic monograph on Bright's disease called Die Bright'sche Nierenkrankheit, Klinik, Pathologie und Atlas.

Pseudo-uremia was described as having symptoms of independent origin, such as cases involving elevated arterial blood pressure.
