Brown began her museum career as an educator in 1977 at the
Brooklyn Museum, thanks to arts employment under the
Comprehensive Employment and Training Act (CETA), which supported many cultural institutions. She advanced to become "manager of school and community programs (1982-1984), and then assistant director for government and community relations (1985-1990) for that institution," then becoming Deputy Assistant Secretary at the Smithsonian. She left the Smithsonian following the mid-1990s failure of a project to establish a
National Museum of African American History as a result of political opposition led by
Jesse Helms. Between her posts at the Smithsonian, Ms. Brown held the office of Director of the Arts and Culture Program at the
Nathan Cummings Foundation. The foundation's president, Lance Lindblom wrote that her work as a grantmaker particularly involved the relationship between art and social justice. Brown shared her career perspective in a 2011 panel session entitled
"Access and Inclusivity in the Museum". ==Education==
