What organization did the woman, who Märta Ulfsdotter was the head lady in waiting of, found?
Margaret I of Denmark Margaret I (Danish: "Margrete Valdemarsdatter" , Norwegian: "Margrete Valdemarsdatter" , Swedish: "Margareta Valdemarsdotter" , Icelandic: "Margrét Valdimarsdóttir" ; 1353 – 28 October 1412), was queen consort of Norway 1363-1380 and Sweden 1363-1364, and later ruler in her own right of Denmark, Norway and Sweden, from which later period there are ambiguities regarding her specific titles. She was the founder of the Kalmar Union, which spanned Scandinavia for over a century. Margaret was known as a wise, energetic and capable leader, earning the nickname "Semiramis of the North", or "the Lady King". Though the latter was a derisive nickname invented by her rival Albert of Mecklenburg, it became widely used in recognition of her capabilities.
Anna Tomaszewicz-Dobrska Anna Tomaszewicz-Dobrska (1854-1918) was the second Polish woman to become a doctor, and the first female Polish doctor to practice in Poland. She obtained her medical degree in 1877 in Zurich. During her fifth year of study in Zurich she worked as an assistant to Professor Edward Hitzig (a German neurologist and psychiatrist) in the Institute for the Mentally Ill. After obtaining her medical degree she worked in Berlin and Vienna for a short time. However, she was not allowed to pass the state exam, which would have given her the right to practice medicine in Poland, and she was refused as a member of the Polish Society of Medicine because she was a woman. She moved to St. Petersburg and passed the state exam there. This allowed her to practice women's health and pediatric medicine within the Polish Kingdom and Russia. In 1882 an epidemic of infection during childbirth broke out in Warsaw, and a few maternity shelters were opened; shelter number 2 (on Prosta Street) was given to Anna to lead, and she led it until 1911. In 1896 she became the first to perform a Caesarean section in Warsaw.
