Spanish Priest and Teacher.
He founded the amazingly clumsy-named Order Of Clerks Regular Of The Poor Schools Of The Mother of God.
This was an organization devoted to providing poor schools. No, not schools of poor quality, but schools for the poor.
The first such establishment offering freebie education for poor children opened in Spain. The curriculum was necessarily of a religious nature, but it was free to attend and had a hundred pupils in its first week.
Before long, a thousand pupils necessitated other schools opening. And here his troubles began. Other members of his Order wanted all the glory and control for themselves. The founder found himself on the scrap heap.
