Born in Nettuno (Rome) on March 21, 1624.
Died in Rome on December 9, 1694.

Educated in the Roman College he entered the Society of Jesus in 1637 and, ordained a priest in 1653, was destined to preaching. He prepared himself for it with an attentive study of the Scriptures and of the Fathers and with the reading of Cicero's Orations. He then preached, from 1661 to 1692, Lentens and missions to the people in most of Italy, enchanting the people and the sovereigns with his heated word and with the fragellations that took place in the pulpit. Above all, the publication of his Quaresimale (Florence 1679) earned him the fame of father of Italian sacred oratory for his rapid, warm, polemical and impetuous eloquence, for the tight and progressive logic of the argumentation and for the classicism of the language and style. In 1692 he was called to the offices of apostolic preacher and penitentiary theologian by Innocent XII.

Don Guanella claims to have received Segneri's Lent, since the days of *college Gallio, "instead of the usual panettone", a Christmas gift from the priest who is a relative of *Gaudenzio Bianchi. A work that then, with reading and assiduous study, became familiar. Some witnesses at the beatification process recall that Don Luigi used another Segnerian work, La manna dell'anima, as a book of meditation and that he also advised his confreres to draw from it passages of Scripture suitable for preaching.
