Aurelia Isabel Henry Reinhardt (April 1, 1877 – January 28, 1948) was an American educator, activist, and prominent member and leader of numerous organizations.

Reinhardt was a peace activist during the First World War, an active member of the Republican Party, and supported the ratification of the Treaty of Versailles as well as the formation of the League of Nations.

A lifelong advocate for the marginalized and dispossessed, she was the recipient of honorary degrees from a number of educational institutions, and has been commemorated through the establishment of a society, fellowship, a university building, and a professorship bearing her name.

After graduating from Boys High School in San Francisco in 1888, she studied at the University of California, Berkeley, completing a bachelor's degree with a major in English literature in 1898.

[a] She taught at Lewiston State Normal School in Idaho[b] beginning in 1903, taking one year off to revise her dissertation for publication, and eventually becoming the head of the English Department.

[3][7][19] During her tenure Mills constructed 17 additional buildings (growing from 11 to 28 total), increased enrollment three-fold in 15 years,[f] and "gained national, even worldwide favor", including admission to the Association of American Colleges and Universities in 1917.

[h] In the 1940s she served as the first female moderator of the American Unitarian Association from 1940 to 1942, which according to contemporary news reports was the first time a large church in the nation had been represented by a woman.

[13] In 1945 Reinhardt was a delegate to the inaugural meeting of the United Nations in San Francisco, and spoke to numerous groups throughout the country, advocating for the value of organizations such as UNESCO.

His brother Paul Henry Reinhardt, an ophthalmologist in Palo Alto, served with the U.S. Navy in the Pacific Theater of the Second World War and later taught ophthalmology at Stanford University.

[27][28] The school's campus also includes the Aurelia Henry Reinhardt Alumnae House, designed by architect Clarence W. W. Mayhew and built in 1949.

[30][31][32] In 1981 the Starr King School for the Ministry introduced the Aurelia Henry Reinhardt Professorship, in order to "ensure a feminist perspective on the faculty".

[33][j] The archives at Mills College hosts the Reinhardt Collection, a compilation of texts related to "women, with a strength in women’s suffrage, birth control, and social issues",[35] and the school also includes the student run Aurelia Reinhardt Historical Society, established to "inspire an appreciation of the history of the Mills community".
