Question: Who was the American political activist that was a supporter of women's suffrage movement and was also the wife of the author who wrote American Slavery As It Is: Testimony of a Thousand Witnesses?
Context: Emma ʻAʻima Aʻii Nāwahī (September 28, 1854 – December 28, 1935) was a Native Hawaiian political activist, community leader and newspaper publisher.  She and her husband Joseph Nāwahī were leaders in the opposition to the overthrow of the Kingdom of Hawaii and they co-founded "Ke Aloha Aina", a Hawaiian language newspaper, which served as an important voice in the resistance to the annexation of Hawaii to the United States.  After annexation, she helped established the Democratic Party of Hawaii and became a supporter of the women's suffrage movement. Angelina Emily Grimké Weld (February 20, 1805 – October 26, 1879) was an American political activist, women's rights advocate, supporter of the women's suffrage movement, and besides her sister, Sarah Moore Grimké, the only known white Southern woman to be a part of the abolition movement.  While she was raised a Southerner, she spent her entire adult life living in the North.  The time of her greatest fame was between 1836, when a letter she sent to William Lloyd Garrison was published in his anti-slavery newspaper, "The Liberator", and May 1838, when she gave a speech to abolitionists gathered in Philadelphia, with a hostile crowd throwing stones and shouting outside the hall.  The essays and speeches she produced in that two-year period were incisive arguments to end slavery and to advance women's rights. Anne Dallas Dudley ("née" Annie Willis Dallas; November 13, 1876 – September 13, 1955) was a prominent activist in the women's suffrage movement in the United States.  After founding the Nashville Equal Suffrage League and serving as its president, she moved up through the ranks of the movement, serving as President of the Tennessee Equal Suffrage Association and then as Third Vice President of the National American Woman Suffrage Association, where she helped lead efforts to get the Nineteenth Amendment to the US Constitution ratified, giving women the right to vote nationwide.  She is especially noted for her successful efforts to get the Nineteenth Amendment ratified in her home state of Tennessee, the final state necessary to bring the amendment into force. American Slavery As It Is: Testimony of a Thousand Witnesses is a book written by the American abolitionist Theodore Dwight Weld, his wife Angelina Grimké and her sister Sarah Grimké, which was published in 1839. Grace Julian Clarke (September 1865–June 18, 1938) was a clubwoman, women's suffrage activist, newspaper journalist, and author from Indiana.  As the daughter of George Washington Julian and the granddaughter of Joshua Reed Giddings, both of whom were abolitionists and members of the U.S. Congress, Clarke's family exposed her to social reform issues at an early age.  She is credited with reviving the women's suffrage movement in Indiana, where she was especially active in the national campaign for women’s suffrage in the early twentieth century.  She is best known for founding and leading the Indiana State Federation of Women's Clubs, the Legislative Council, and Indiana's Women's Franchise League (an affiliate of the National American Woman Suffrage Association and the predecessor to the League of Women Voters of Indiana).  Clarke was the author of three books related to her father's life, and was a columnist for the "Indianapolis Star" from 1911 to 1929. The women's suffrage movement in Washington State was part of the broader Women's suffrage movement.  In Washington, women gained and lost the right to vote repeatedly. Adeline E. Knapp (March 14, 1860 – c. June 1909) was an American journalist, author, social activist, environmentalist and educator, who is today remembered largely for her tempestuous lesbian relationship with Charlotte Perkins Gilman.  In her lifetime, Knapp was known as a fixture of the turn-of-the-century San Francisco Bay Area literary scene.  An outspoken writer who often addressed controversial topics in her columns for the "San Francisco Call", Knapp wrote on a wide range of subjects from livestock to the Annexation of Hawaii.  Though often drawn to progressive causes like child labor and conservation, Knapp also tended to espouse reactionary views, as evidenced by her anti-Chinese sentiments and criticisms of the women's suffrage movement.  At a time when many American women were joining the movement to extend political and voting rights to women, Knapp spoke in state senate hearings in New York expressing doubts about the benefits of suffrage to women, and she allowed her speeches and letters on the topic to be used as propaganda by the anti-suffragism movement.  Knapp was also the author of numerous short stories, as well as a novel set in the Arizona desert—works reflecting her outdoor enthusiast sensibilities, keen intellect, and interest in Western regionalism.  These works, though praised in her lifetime, today have few readers among enthusiasts of Western fiction. The People's Suffrage Federation was a British Adult Suffrage organisation.  It was created by a merger of the Co-operative Women's Guild and the Women's Labour League in 1909.  Led by Margaret Llewelyn Davies, who was the former Co-operative Women's Guild general secretary.  The group believed that the Women's Suffrage movement was being damaged by class divisions, such as those which resulted in the split between the Women's Social and Political Union and the Women's Freedom League.  They also thought that universal suffrage would be more popular with the liberal Government as it was likely that if only privileged women were granted voting rights, then this would likely aid the conservative vote in future elections. History of Woman Suffrage is a book that was produced by Elizabeth Cady Stanton, Susan B. Anthony, Matilda Joslyn Gage and Ida Husted Harper.  Published in six volumes from 1881 to 1922, it is a history of the women's suffrage movement, primarily in the United States.  Its more than 5700 pages are the major source for primary documentation about the women's suffrage movement from its beginnings through the ratification of the Nineteenth Amendment to the U.S. Constitution, which enfranchised women in the U.S. in 1920.  Written from the viewpoint of the wing of the movement led by Stanton and Anthony, its coverage of rival groups and individuals is limited. Suffrage drama (also known as Suffrage Plays or Suffrage theatre) is a form of dramatic literature that emerged during the British women’s suffrage movement in the early twentieth century.  Suffrage performances lasted approximately from 1907-1914.  Many suffrage plays called for a predominant or all female cast.  Suffrage plays served to reveal issues behind the suffrage movement.  These plays also revealed many of the double standards that women faced on a daily basis.  Suffrage theatre was a form of realist theatre, which was influenced by the plays of Henrik Ibsen.  Suffrage theatre combined familiar everyday situations with relatable characters on the stage in the style of realist theatre.
