Named after Wilhelm and Karl Liebknecht, father and son.
Wilhelm Liebknecht (1826–1900) was a pioneer of social democracy; his son Karl (1871–1919) was murdered in Berlin. The lane, formerly Dürauergasse, first took their name in 1927. In December 1934 it was renamed Eberhartgasse; the name Liebknechtgasse returned in 1953.
