A Catholic high school in Lombard, Illinois was planned by the Christian Brothers in 1963. Pope Paul Vl, whose name was Giovanni Battista Montini (John Baptist Montini), was elected to the Papacy that same year. A brilliant man, deeply spiritual, reserved and gentle, he was of "infinite courtesy." He was one of the most traveled popes at that time, and the first to visit five continents.
In his honor, the Chrisitan Brothers named the school Montini Catholic High School. Construction of the buildings took place in 1965 and 1966. In September of 1966, Montini opened its doors to 217 freshmen. The first commencement exercises were held on June 1, 1970. Since then, Montini Catholic has graduated more than 6,000 students, over 98% of whom have gone on to college.
