Carl Jakob Adolf Christian Gerhardt studied in Würzburg, obtaining his doctorate in 1856. He was an assistant under Heinrich von Bamberger (1822-1888) and Franz von Rinecker (1811-1883) in Würzburg, and under Wilhelm Griesinger (1817-1868) in Tübingen. He was habilitated as Privatdozent in Würzburg in 1860, and from November 1861 was professor of medicine and head of the internal department in Jena. He assumed the same position in Würzburg 1872, and in 1885 as Friedrich Theodor von Frerichs’(1819-1885) successor in Berlin. In Berlin he established the second internal clinic at the Charité. He held the position of prorector or rector at all three universities to which he was attached.

In Berlin Gerhardt worked with Paul Ehrlich (1854-1915), who was his assistant, but Ehrlich became unhappy because Gerhardt wanted him to become more clinically involved.

In 1892 he described erythromelalgia, called Gerhardt’s disease, In 1863 he described Gerhardt’s law (on vocal paralysis) stating that in paralysis of the periodically recurring laryngeal nerve, the vocal cords assume a position between abduction and adduction. He used iron chloride to detect acetone in diabetes (Gerhardt’s reaction). Weir-Mitchell described erythromelalgia also in 1872.

Gerhardt was a founder of pediatrics, and editor of one of the most authoritative textbooks on the subject, Handbuch der Kinderkrankheiten, to which he contributed several articles based on his own experiences. He was also a prolific contributor to the Archiv für klinische Medicin.

His son was the physician Dietrich Gerhardt (1866-1921).
