During World War II, O'Donnell offered Notre Dame's facilities to the armed forces.
The navy accepted his offer and installed Naval ROTC units on campus as part of the V-12 Navy College Training Program.
Soon after the installation there were only a few hundred civilian students at Notre Dame.
O'Donnell also continued O'Hara's work with the graduate school.
