Saint Ignatius of Loyola 
The autobiography of St. Ignatius 

The Autobiography of St. Ignatius is considered the most valuable record of the great Founder of the Society of Jesus, the Jesuits, also known as Ignatius of Loyola.

Saint Ignatius of Loyola (23 October 1491 – 31 July 1556) was a Spanish Basque Catholic priest and theologian, who co-founded the religious order called the Society of Jesus (Jesuits) and became its first Superior General at Paris in 1541.
The Jesuit order served the Pope as missionaries, and they were bound by a vow of special obedience to the sovereign pontiff in regard to the missions. They therefore emerged as an important force during the time of the Counter-Reformation.
Ignatius is remembered as a talented spiritual director. He recorded his method in a celebrated treatise called the Spiritual Exercises, a simple set of meditations, prayers, and other mental exercises, first published in 1548.

Ignatius was beatified in 1609, and then canonized, receiving the title of Saint on 12 March 1622. His feast day is celebrated on 31 July. He is the patron saint of the Basque provinces of Gipuzkoa and Biscay as well as the Society of Jesus, and was declared patron saint of all spiritual retreats by Pope Pius XI in 1922. Ignatius is also a foremost patron saint of soldiers.
