Belva Lockwood
1830–1917
Opened the Supreme Court to women — and became the first to argue there.
Belva Lockwood was an attorney and political activist who dismantled legal barriers that had long excluded women from the American justice system.
Denied entry to the bar despite completing her legal education, Lockwood lobbied Congress directly - successfully securing legislation in 1879 that allowed qualified women to practice before the U.S. Supreme Court. That same year, she became the first woman admitted to argue cases at the nation’s highest judicial level, stepping into a chamber that had been structurally closed to her sex.
Her legal career extended beyond symbolic entry. In 1906, Lockwood represented the Cherokee Nation before the Supreme Court, winning a $5 million settlement for unpaid treaty obligations - one of the largest Indigenous claims victories of its era.
She also worked to codify economic equity within federal employment, drafting and campaigning for legislation passed in 1872 that mandated equal pay for equal work for female government employees - an early statutory challenge to gendered wage disparity.
Lockwood’s career redrew the operational boundaries of American law, establishing women not only as participants in the legal system, but as advocates capable of shaping its outcomes.
