Father Nugent was principal of Nativity from 1955 to 1967. During his tenure, the Allentown Diocese was formed from an area that had formerly been part of the Philadelphia Archdiocese. In 1960, Catholic schools in Schuylkill, Berks, Carbon, Lehigh, and Northampton Counties became part of the new Allentown Diocese. In 1961, a senior named John Vincent Egan graduated and enrolled at Saint Charles Seminary. He was later to become Nativity's principal and work with faculty members who had been his teachers!
