Which founder is known for their membership in the Baltimore Branch of the National Association of College Women?

The correct choice is attributed to Vashti Turley Murphy, who is recognized for her involvement with the Baltimore Branch of the National Association of College Women. This organization was significant in the early 20th century, focusing on addressing issues pertinent to women in higher education. Murphy's engagement with the organization underscores her commitment to advancing educational opportunities for women, especially women of color, which aligns with the values of Delta Sigma Theta Sorority, Incorporated.

In the context of the other founders, while they each played vital roles in the establishment and development of Delta Sigma Theta, they are not specifically noted for a similar affiliation with that particular branch of the National Association of College Women. Thus, Murphy's connection highlights her active participation in advocacy and empowerment through educational initiatives, portraying her as a pioneering figure in both the sorority and the broader movement for women's rights in education.
