Many famous Catholic men from all over the world have been Knights of Columbus. In the United States, some of the most notable include John F. Kennedy, Ted Kennedy, Al Smith, Sargent Shriver, Samuel Alito, John Boehner, Ray Flynn, Jeb Bush, and Sergeant Major Daniel Daly, a two-time Medal of Honor recipient, once described by the commandant of the U.S. Marine Corps as "the most outstanding Marine of all time."
In the world of sports, Vince Lombardi, the famed former coach of the Green Bay Packers; wrestler Lou Albano; James Connolly, the first Olympic gold-metal champion in modern times; Floyd Patterson, former heavyweight boxing champion; and baseball legend Babe Ruth were all Knights.
Many notable clerics are also Knights, including Cardinal William Joseph Levada, prefect of the Congregation for the Doctrine of the Faith; Cardinal Sean O'Malley, Archbishop of Boston; and Cardinal Jaime Sin, former Archbishop of Manila.
On October 5, 2006, Bishop Rafael Guizar Valencia (1878-1938) was canonized by Pope Benedict XVI in Rome. In 2000, six other Knights were declared saints by Pope John Paul II.
