Final answer:
The Sigma Pi alumnus who became the NIC president was also the first president of Clark University, marking a significant role in the history of higher education in Massachusetts.
Step-by-step explanation:
The Sigma Pi alumnus who served as the president of the National Interfraternity Conference (NIC) is also notable for becoming the first president of Clark University in Massachusetts upon its founding.
While the question does not specify the individual by name, this achievement is historically significant because Clark University was established with a strong research orientation and emphasis on graduate education, making the position of its first president a remarkable point in educational history. The leadership roles in both the fraternity system, through Sigma Pi and the NIC, and the university system demonstrate the broad impact this individual had on higher education and student life.
