Francesco Spinelli was an Italian Catholic priest born in Milan in 1853. After his ordination in Bergamo, he dedicated his ministry to Eucharistic devotion. Following a difficult period involving a religious institute he co-founded with Geltrude Comensoli, he moved to Cremona. There, he established the Sisters Adorers of the Blessed Sacrament, a congregation focused on adoration. He died in Rivolta d'Adda in 1913 and was later recognized as a saint by the Catholic Church.
