Rosa played a pivotal role in Alpha Kappa Alpha Sorority, Inc., the first sorority founded by African American women. Though her classification as a lower-classman prevented her from being a Founder, Rosa’s influence was undeniable. She was closely connected to the organization’s development, sharing the exciting news of AKA's approval to become a sorority in November 1907 with her cousin, Eugene Kinckle Jones, a co-founder of Alpha Phi Alpha Fraternity, Inc. She and fellow Alpha woman Pauline Ray also helped to continue changes on other campuses as well. 

Rosa Vassar & Pauline played a significant role in the fight to integrate Sage Hall at Cornell University, a landmark moment in the early struggle for racial equality in higher education. As an African American student at Cornell during the early 1900s, the women faced the institutionalized racism and social barriers that were commonplace in predominantly white institutions. Sage Hall, a dormitory designated for women, initially re-barred African American students from residing there, reflecting broader racial segregation practices of the time. 

Determined to challenge this exclusion, Rosa, alongside other African American students and allies, advocated for her right to live in Sage Hall. Their persistence and courage in confronting the university’s policies were pivotal in breaking down this barrier. Rosa’s success in gaining residence at Sage Hall was not merely a personal victory but a significant step toward greater inclusivity at Cornell. It set a precedent that challenged the discriminatory norms of the era and paved the way for future African American students to access equal opportunities on campus.

This battle was emblematic of Rosa’s resilience and commitment to justice, qualities that would define her lifelong contributions as an educator, community leader, and member of Alpha Kappa Alpha Sorority, Inc. 

Rosa Vassar Rodgers, along with esteemed educators such as Norma Clayton, Virgie Vassar, and Miss Davis, made the significant and principled decision to leave the Lynchburg school system before 1920 due to pervasive racial discrimination. At the time, African American educators in the segregated South often faced systemic inequities, including unequal pay, lack of resources, and limited professional advancement compared to their white counterparts. These discriminatory practices not only hindered their ability to teach effectively but also highlighted the broader racial injustices within the educational system.

The decision to leave was not taken lightly. Rosa, Norma, Virgie, and Miss Davis were all deeply committed to education and the empowerment of African American youth. However, their departure was a powerful statement against the entrenched racism of the era. By choosing to leave, they demonstrated their unwillingness to accept inequity and brought attention to the structural changes needed within the education system.

Their collective decision also reflects the broader struggle of African American educators during this period to assert their dignity and demand fair treatment. Rosa’s departure from Lynchburg was consistent with her lifelong commitment to justice, equality, and the pursuit of opportunities that aligned with her principles. Following this move, Rosa continued her impactful career, teaching in other locations such as Camden, New Jersey, and Richmond, Virginia, where she became the first African American teacher at Richmond's colored high school, further cementing her legacy as a trailblazer in education and civil rights.

As a charter member of Alpha Kappa Alpha's Omega Omega chapter, Rosa was a dedicated leader. She served as editor of The Ivy Leaf, the sorority’s official publication, during its early years when it was published biennially. Her love for literature and the arts was evident, as she offered prizes for poetry and editorials, enriching the cultural life of the organization.

A talented songstress and educator, Rosa’s contributions extended beyond her sorority. 

After marriage, Rosa gave birth to a daughter named Leonora. Throughout her life, Rosa balanced her professional and personal commitments with grace, remaining a steadfast advocate for education, equity, and the arts.

Rosa Vassar Rodgers passed down a legacy of leadership, creativity, and courage. Her trailblazing efforts, particularly as an educator and a leader within Alpha Kappa Alpha Sorority, Inc., continue to inspire generations. She was a true pioneer whose life exemplified the power of education and community to transform lives.
