Background: Patsy Matsu Takemoto Mink (Zhu Ben  matsu, Takemoto Matsu, December 6, 1927 - September 28, 2002) was an American lawyer and politician from the U.S. state of Hawaii. Mink was a third generation Japanese American and member of the Democratic Party. She also was the Assistant Secretary of State for Oceans and International Environmental and Scientific Affairs. Mink served in the U.S. House of Representatives for a total of 12 terms, representing Hawaii's first and second congressional districts.
Context: While attending the University of Chicago Law School, Patsy met hydrologist John Mink while playing bridge at the International House. He would become her husband and lifelong partner. Unable to find work as a married, female, Asian-American attorney, she returned to her student job at the University of Chicago Law School library while her husband found work immediately with the United States Steel Corporation. In 1952, Patsy gave birth to daughter Gwendolyn (Wendy), who later became a prominent author and educator on labor and women's issues. The family soon moved Hawaii in August 1952.  By law, Patsy was required to take the residency status of her husband after marriage and needed to re-establish her Hawaiian residency in order to prove that she was eligible to take the Hawaii bar exam. After challenging the statute as sexist, Hawaii's attorney general ruled that since she had not ever physically resided in Pennsylvania, she had not assumed her husband's Philadelphia residency status.  After passing the bar exam in June 1953, Mink continued to face gender discrimination in finding work as an attorney in the private or public sector. She created a solo practice with the help of her father. She was the first Japanese woman to practice law in Hawaiian territory. Mink founded the Everyman Organization, a group that served as the hub of the Young Democrats club on Oahu. She was elected chairman of the territory-wide Young Democrats, "a group that would wield a remarkable influence over Hawaiian politics for several decades." In 1954, Patsy worked to help elect John A. Burns to Congress. The following year, she worked as staff attorney during the 1955 legislative session and drafted statutes and observed the inner-workings of the legislature.  As the Territory of Hawaii debated statehood in 1956, Mink was elected to the Hawaii Territorial Legislature representing her district in the territorial House of Representatives. In 1958, she was elected to serve in the territorial Senate. In 1959, Hawaii became the 50th state of the Union. From 1962-1964, Mink served in the Hawaii State Senate.  At the 1960 Democratic National Convention, a speech by Mink, a Hawaiian delegate, persuaded two-thirds of the party to keep their progressive stance on civil rights.
