  • The milestone did not end racial or gender exclusion in public accounting.

Mary T. Washington built a Chicago practice serving businesses and nonprofit organizations while helping other Black accountants obtain the experience that licensing pathways required. Her 1943 certification therefore marks more than a first.

The case shows how professional capacity compounds. A person who opens a firm, trains staff, and signs qualifying experience can alter later entrants' opportunity set even when wider institutions change slowly.
