He studied medicine in Munich, and in 1831 took part in a scientific expedition to Egypt.
Practice
While in Egypt he was appointed by viceroy Mehmed Ali as chair of anatomy and physiology at the medical school in Abuzabel, near Cairo. This institution had recently been established in 1825 by French physician Antoine Clot. In 1832 he returned to Europe and studied with Francesco Flarer in Pavia. Soon afterwards he returned to Cairo as director of a military hospital. Subsequently, he served as a professor of ophthalmology as well as director of the hospital at Kasr al Aini. In 1839 he became a physician to Egyptian royalty, and was given the title of bey. In 1860 he returned to Europe, eventually settling in Paris, where he performed anthropological research. After the outbreak of the Franco-Prussian War, he moved to Pisa, where he worked as a private scholar until his death in 1882.
He is remembered today for his research in anthropology, linguistics, ethnology and ethnography. He published over 120 works in these fields, and in 1865 was appointed president of the Société d’Anthropologie in Paris.
Pruner studied the racial structure of Negros in Egypt. In a book which he wrote in 1846 he claimed that Negro blood had a negative influence on the Egyptian moral character. He published a monograph on Negros in 1861. He claimed that the main feature of the Negros skeleton is prognathism, which he claimed was Negros relation to the ape. He also claimed that Negros had very similar brains to apes and that Negros have a shortened big toe which is a character which connects the Negros close to apes.
