Hannah Greenebaum Solomon's lifelong activism on behalf of
women and children stemmed from her deep conviction for
social justice and universal brotherhood.

At Chicago's 1893 World's Columbian Exposition, Solomon
brought together Jewish women to study Judaism and apply
their knowledge to the improvement of society through social reform. This led her to found the National Council of Jewish Women, which assisted Jewish immigrants. She lived at 4060 South Lake Park Avenue.

In 1897, Solomon created the Bureau of Personal Service, which provided immigrants with food and shelter, aided delinquents, and instituted work and training programs. Solomon also conducted one of the first surveys of schools and other public agencies available in the Jewish immigrant district of Chicago.

Solomon worked on behalf of Jane Addams's Hull-House and for the establishment of a juvenile court system in Cook County.

In 1904, Solomon and Susan B. Anthony represented the United States at the International Council of Women in Berlin. Fluent in both French and German, Solomon interpreted for Anthony as the council discussed ways to advance the position of women around the world.
