I graduated from Loyola High School in Los Angeles. Reese graduated in 1962 and taught there as a scholastic (Jesuits must teach before they can become ordained). Mr Reese SJ was called Peewee because he had the same last name as the famous baseball player. Reese came from a rich family. There were a lot of rich kids there, including sons of movie stars. Michael Reagan flunked out.
His nickname was complimentary since Peewee Reese was a hero to many of us baseballers. We had scholastics as well. Valedictorian of my year is the Stanford prof and former Representative out your way Tom Campbell. So you had Michael Reagan, which was much preferable to our illuminati: the Daley brothers.
