Erna Lang (born Erna Demuth: 30 June 1892 – 18 May 1983) was a German activist participant in the November Revolution and politician.
Between 1913 and 1918 she was married to Max Halbe who was killed in the war. Her second marriage, to Joseph Lang, took place in 1941. Therefore, sources covering her political and later activities may identify her as Erna Halbe or as Erna Lang.[1][2][3][4]
