Carl Jakob Adolf Christian Gerhardt

Carl Jakob Adolf Christian Gerhardt (there are several variations regarding the arrangement of his 3 middle names; 5 May 1833 – 22 July 1902) was a German internist born in Speyer.

In 1885 he was successor to pathologist Friedrich Theodor von Frerichs (1819–1885) at the Charité in Berlin, where he established the second internal medicine clinic.

Gerhardt is remembered for his pioneer work in pediatrics, being the editor of an influential textbook on childhood diseases called Handbuch der Kinderkrankheiten.

[2] He also performed important research involving auscultation and percussion, and conducted investigations of diabetes.

[3] In 1892 he provided an early description of erythromelalgia, a condition once referred to as "Gerhardt’s disease".
