Caroline Katzenstein (1888 – January 31, 1968) was an American suffragist, activist, advocate for equal rights, insurance agent, and author.

In addition to Katzenstein, the following women were a part of this tour: Lillian Ascough, Abby Scott Baker, Harriot Stanton Blatch, Lucy Burns, Agnes Campbell, Anna Constable, Sarah T. Colvin, Edith Goode, Jane Goode, Florence Bayard Hilles, Julia Hurlbut, Winifred Mallon, Dorothy Mead, Agnes Morey, Katherine Morey, Gertrude B. Newell, Mrs. Percy Read, Ella Riegel, Elizabeth Rogers, Mrs. Townsend Scott, Helen Todd, and Margaret Whittemore.

[7] Katzenstein remained active in the Philadelphia suffrage movement when the Nineteenth Amendment to the United States Constitution was ratified on August 26, 1920.

Katzenstein was still involved with the NWP following the ratification of the Nineteenth Amendment, and when the Women Teachers Organization of Philadelphia approached the party for aid in their fight for equal pay, she offered to help publicize their efforts.

[5] The Woodruff and Finegan bills were passed in the early 1920s, ensuring pay parity between male and female teachers in Philadelphia.

As a representative of the World Woman’s Party, Katzenstein served on the Women’s Joint Legislative Committee with Alice Paul in 1943.

During the 1950s Katzenstein poured her energy into writing, both formally and informally: in 1955 she published her first and only book, Lifting the Curtain: the State and National Woman Suffrage Campaigns in Pennsylvania as I Saw Them (1955), in which Alice Paul wrote the preface.

[5] At the same time, she wrote to leading politicians, including Presidents Dwight D. Eisenhower, Harry S. Truman, and Richard M. Nixon, and Senators Robert Taft, John F. Kennedy, and Joseph Sill Clark, encouraging them to support the ERA.
