Karl Konrad Friedrich Wilhelm Lachmann

Karl Konrad Friedrich Wilhelm Lachmann (German: [ˈlaχman]; 4 March 1793 – 13 March 1851) was a German philologist and critic. He is particularly noted for his foundational contributions to the field of textual criticism.

Lachmann was born in Brunswick, in present-day Lower Saxony. He studied at Leipzig and Göttingen, devoting himself mainly to philological studies. In Göttingen, he founded a critical and philological society in 1811, in conjunction with Dissen, Schulze, and Bunsen. In 1815, he joined the Prussian army as a volunteer chasseur and accompanied his detachment to Paris, but did not see active service. In 1816, he became an assistant master in the Friedrichswerder gymnasium at Berlin, and a Privatdozent at the university. The same summer he became one of the principal masters in the Friedrichs-Gymnasium of Königsberg, where he assisted his colleague, the Germanist Friedrich Karl Köpke, with his edition of Rudolf von Ems' Barlaam und Josaphat (1818), and also assisted his friend in a contemplated edition of the works of Walther von der Vogelweide.
