You can read about him in the Ferdinand Holbock book "New Saints and Blesseds of the Catholic Church" Ignatius Press 2000, which I highly recommend and enjoy very much. The chapter on him is so very moving and gives great detail.
I found this website also gives a wonderful account of this incredible holy man.
While he suffered from great physical deformity he never lost his faith, he had an ardent love for Mary, and he sat in a tiny unheated hut for forty years, hearing confessions from anyone and all.
If you tire, as I do, reading all that is phony, fake and manipulated day after day, refresh your eyes with reading about this dear saint who was the "real thing" throughout his mortal life.
