Louise Frankel Rosenfield Noun (March 7, 1908 – August 23, 2002)[1] was a feminist, social activist, philanthropist, and civil libertarian.

As president of the Iowa Civil Liberties Union from 1964 to 1972, she was actively involved and helped fund the Tinker v. Des Moines Independent Community School District case.

In a 1985 interview with Howard Simmons, Noun asserted that her father was more reticent and that her mother "ran the show with a firm hand.

Noun began her art collection at age thirteen when she was given an oil painting by Harry Lachman on her birthday, a story that was published in the Des Moines Register.

Other works by female artists collected by Noun include Natalia Goncharova, Hannah Höch, Frida Kahlo, Käthe Kollwitz, Gabriele Münter, Agnes Pelton, and Marguerite Zorach.

[7] In 1944, Louise Noun joined the Des Moines chapter of the League of Women Voters and served as president in 1948–1949, igniting her long career of activism and philanthropy.

In the late 1960s, Noun helped finance the landmark U.S. Supreme Court students' rights case Tinker v. Des Moines Independent Community School District, with her brother Joseph Rosenfield.

[2] To fund the archives, Noun sold Frida Kahlo's 1947 painting "Self-Portrait with Loose Hair" at Christie's New York for 1.65 million dollars.

[10] The University of Iowa Foundation undertook fundraising to contribute half a million dollars for the archives, which opened in 1992.

[9] The Louise Noun Library opened in March 2017 at Des Moines' Young Women's Resource Center.
