Ernestine Lutze (17 June 1873 – 27 April 1948) was a German trade unionist and politician. In 1919 she was one of the 36 women elected to the Weimar National Assembly, the first female parliamentarians in Germany. She remained a member of parliament until the following year.
Lutze was born Ernestine Elsterwerda in Merzdorf in 1873.[1] She attended primary school in Dresden and Großenhain,[1] and began working as a maid aged nine. She later became a florist and a board member of the Flower Worker's Association and married painter Karl Otto Lutze. In 1911 she attended trade union school in Berlin.[1] Back in Dresden, she became a committee member of the regional health insurance fund and in 1917 was appointed to Dresden City Council's housing committee. After the outbreak of the German Revolution in 1918, she became a member of the city's Workers' and Soldiers' Council.
Having been a speaker for the Social Democratic Party (SPD) for several years, in January 1919 she was elected to the Weimar National Assembly from the Saxony I constituency as a representative of the SPD. She lost her seat in the 1920 Reichstag elections. In 1926 she joined the new Old Social Democratic Party, becoming a member of the executive committee of the party's East Saxony branch. Between 1926 and 1929 she served as a city councillor in Dresden.[2]
She died in Dresden in 1948.
