It has been done three times: by Minnesota, Alabama and Notre Dame.However, in the early days it was common to have "multiple" national championships, and I believe one year Alabama and Notre Dame both claimed a national championship as part of their series.
Notre Dame is credited with 13 national championships. The years were 1924, 1929, 1930, 1938, 1943, 1946, 1947, 1949, 1953, 1966, 1973, 1977, and 1988. ==actually, in division 1A, the NCAA does not award a championship. The reference made to thirteen championships here are "POLL" championships. The early ones especially have to be taken with a healthy dose of skepticism. Notre Dame has not won any NCAA Football National Championships. The NCAA does not award a national football title in Division 1A football because there is not a sanctioned NCAA playoff system in place as there is in most other NCAA sports. The football Division 1A National Football title is a "mythical" title being decided by as many as several dozen different polling groups over the past 150 odd years. There have been as many as five national champions voted in a single year in the past. The current BCS National Title is not recognized by the NCAA either.
