Marianne Hainisch was born to wealth and lived in such her entire life, but she noticed the situation of other less fortunate women around her, and saw a need for social reform. She became very active in the Austrian women's rights and education movement. She founded the National Council of Women in Austria and also became a member of the International Council of Women. The recognition of a "Mother's Day" holiday in Austria can be traced to her efforts.
