 Though she had limited schooling, she was the first American woman to rebel against discrimination towards women in industry, refusing to accept a woman's pay rate after doing a man's job.
 Greene was also an early champion of the temperance and suffrage causes in her writing and speaking engagements.
 She died in 1900.

 All three were associated with the Council of Federated Organizations (COFO) and its member organization the Congress of Racial Equality (CORE).
 They had been working with the Freedom Summer campaign by attempting to register African Americans in Mississippi to vote.
