Caroline Katzenstein (1888-1968) was a leader in the Pennsylvania suffrage movement. She served in official positions for the Equal Franchise Society of Philadelphia, the National American Woman Suffrage Association, and the National Woman’s Party. After women won the vote in 1920, Katzenstein continued to fight for women’s rights and lobbied tirelessly for the passage of the Equal Rights Amendment for over twenty years. In 1919, Katzenstein used her expertise in publicity to aid the Women Teachers Organization of Philadelphia in their efforts to increase salary for women teachers. Additionally, Katzenstein was a successful insurance agent for the Equitable Life Insurance Society of New York, the Massachusetts Bonding and Insurance Company (Philadelphia Branch), and the Philadelphia Life Insurance Company.
