Joachim Marquardt
Karl Joachim Marquardt (19 April 1812 – 30 November 1882) was a German historian and writer on Roman antiquities. In his later life he was Rector of the Ernestine Gymnasium, Gotha. Biography Marquardt was born at Danzig. He studied at Berlin and Leipzig, held various educational appointments from 1833 onwards at Berlin, Danzig, and Posen, and became in 1859 head of the gymnasium in Gotha, where he died in 1882. The dedication of his treatise Historiae equitum romanorum libri quatuor (1841) to Lachmann led to his being recommended to the publisher of Wilhelm Adolf Becker's Handbuch der römischen Alterthumer to continue the work on the death of Becker in 1846. The work took twenty years to complete, and met with such success that a new edition was soon called for. Finding himself unequal to the task single-handed, Marquardt left the preparation of the first three volumes (Römisches Staatsrecht) to Theodor Mommsen, while he himself contributed volumes V-VI (Römische Staatsverwaltung, 1873–1878) and volume VII (Das Privatleben der Römer, 1879–1882).

Marquardt died in Gotha, while still in office as Rector of
