Arabella Mansfield (May 23, 1846 - August 1, 1911), born Belle Aurelia Babb, became the first female lawyer in the United States in 1869, admitted to the Iowa bar; she made her career as a college educator and administrator. Despite an Iowa state law restricting the bar exam to males, Mansfield had taken it and earned high scores. Shortly after her court challenge, Iowa amended its licensing statute and became the first state to accept women and minorities into its bar.
During her career, Mansfield worked primarily as an educator and activist, teaching at Iowa Wesleyan College and DePauw University. At the latter, she also became a university administrator, serving successively as dean in the 1890s of two different schools.
Belle Aurelia Babb (known as Belle) was born in 1846 on a family farm in Burlington, Iowa, as the second child to Mary (Moyer) (1820-1895) and Miles Babb. Her older brother, Washington Irving Babb, born in 1844 and named after the prominent New York author, was her lifelong friend. While Belle was young, her father left for California, attracted by the gold rush, and abandoned his family. They learned that in 1852, he became superintendent of the Bay State Mining Company.
Mary Babb moved with their two children to Mount Pleasant, Iowa, where they attended local schools. (Clara Foltz, the first woman lawyer to be accepted to the bar on the West Coast, also grew up in Mount Pleasant around this time.)
In 1862, Babb started her studies at Iowa Wesleyan College in Mount Pleasant. There she began using the name Arabella (previously, she had gone by her given name of Belle). As many men were leaving to fight in the American Civil War, universities were admitting more women students and hiring them as teachers. Arabella Babb graduated in three years as valedictorian; her brother Washington Babb was salutatorian in the same class.
Babb taught at Simpson College in Indianola, Iowa for a year. She returned to Mount Pleasant to marry her college sweetheart, John Melvin Mansfield, a young professor at Iowa Wesleyan. He encouraged her in her ambition to study law. Arabella Mansfield "read the law" as an apprentice in her brother Washington's law office, after he had passed the bar and established his practice. Although by Iowa law the bar exam was restricted to "males over 21," Arabella Mansfield took the exam in 1869, passing it with high scores.
In 1869, Iowa became the first state in the union to admit women to the practice of law after Mansfield challenged the state law excluding her. The Court ruled that women may not be denied the right to practice law in Iowa, admitting Mansfield to the bar. Mansfield was sworn in at the Union Block building in Mount Pleasant that year.
Although admitted to the bar, Mansfield did not practice law, concentrating on college teaching and activist work. She taught at Iowa Wesleyan College, followed by DePauw University in Greencastle, Indiana. In 1893 she was selected as Dean of the School of Art at DePauw, and in 1894 as Dean of the School of Music. In 1893, Mansfield joined the National League of Women Lawyers.
Mansfield died in 1911 in Aurora, Illinois, before getting to see the suffrage movement's ultimate achievement: passage of the Nineteenth Amendment to the United States Constitution, effective in 1920.
