Final answer:
C.C. Poindexter is connected with the early days of Alpha Phi Alpha Fraternity but is not listed as a founding Jewel because he left Cornell University before the fraternity was officially established and did not join it.
Step-by-step explanation:
C.C. Poindexter is a figure associated with the early history of the Alpha Phi Alpha Fraternity, which is the first intercollegiate Greek-letter fraternity established for African American men. Poindexter is considered significant because he led the early literary society discussions that eventually led to the formation of the fraternity at Cornell University in 1906.
However, C.C. Poindexter is not listed as one of the seven founders, or "Jewels," of Alpha Phi Alpha because he left Cornell shortly after the initial meetings and before the fraternity was fully established and did not pursue membership of the fraternity.
The official "Jewels" are Henry Arthur Callis, Charles Henry Chapman, Eugene Kinckle Jones, George Biddle Kelley, Nathaniel Allison Murray, Robert Harold Ogle, and Vertner Woodson Tandy, who continued the work of establishing the fraternity and are recognized for their efforts in making it a national organization.
