Meta Quarck-Hammerschlag (born Meta Heinrichs: 21 December 1864 – 11 August 1954) was a German social reformer and women's rights activist. She had a number of 'firsts' to her name: she was the first woman to serve as a member of the Frankfurt city council ("Magistrat"), which she did between 1919 and 1924 and again between 1926 and 1933. Through that period the focus of her work remained, as before, on welfare issues and youth work.
