Anderson (May 21, 1901 – February 5, 1993) was an African-American playwright and librarian.
She was of Native American, Jewish, East Indian, Swedish, and other European ancestry (including one grandparent who was a Confederate general); one of her grandparents was of African descent, born in Madagascar.
Despite her own identification of her race as "American", she was perceived to be African-American by others.
Influenced by Ida B.
Wells and the lack of black history teachings in school, Regina became a key member of the Harlem Renaissance.
