St Ignatius Loyola is the founder of the Jesuits.
Son of a noble and rich family, Ignatius led a life typical of young nobles of his time, until he received a wound at the battle of Pamplona that left him with a limp. He began to read the mystic writers and changed his lifestyle to one of severe self-mortification at Manresa. It was there that he began to compile the Spiritual Exercises
In 1523 he left on a pilgrimmage to Jerusalem and then to Paris University for study. Its in Paris, with his companions, that he formed the Society of Jesus, what we now call the Jesuits, today. By the time of his death, there were already more than 1000 members in the order.
