Which of the following figures is an honorary member of Delta Sigma Theta?

Ruby Dee is recognized as an honorary member of Delta Sigma Theta Sorority, Inc. Honorary membership is awarded by the sorority to individuals who have made significant contributions to both society and the African American community, and Ruby Dee fits this criterion perfectly. She was an accomplished actress, poet, playwright, and civil rights activist, dedicating her life to social justice and advocacy for African American rights. Her work, particularly during the Civil Rights Movement, aligns with the values and mission of Delta Sigma Theta, which emphasizes public service and community engagement.

While Michelle Obama has also been a role model and advocate for many causes, and both Rihanna and Florence Nightingale are well-known figures in their respective fields, they do not hold honorary membership in Delta Sigma Theta. Hence, Ruby Dee stands out as a prominent honorary member recognized for her impactful contributions.
