Final answer:
The standing historian of Pi Kappa Phi's identity and chapter designation are internal fraternity details that are variable and cannot be provided without accessing Pi Kappa Phi's records.
Step-by-step explanation:
The question of who is the standing historian of Pi Kappa Phi and the individual's chapter designation is specific to a particular fraternity and would typically require internal knowledge of Pi Kappa Phi's current officers and members. As Pi Kappa Phi is a Greek-letter fraternity with numerous chapters across different colleges and universities, the identity of the standing historian can vary over time and is not part of the public domain knowledge that can be answered without accessing the fraternity's internal records.
It's important to note that fraternities like Pi Kappa Phi are part of a larger network of Greek organizations that sometimes collaborate through umbrella organizations such as the National Pan-Hellenic Council, which oversees several International Greek fraternities and sororities and promotes interaction among the nine historically African American, international Greek lettered fraternities and sororities.
