founder of the Congregation of St Joseph. Born and educated in Turin, he was ordained priest in 1851 and then devoted himself to the education of working-class boys through directing the Oratory of St Louis, fostered by John Bosco. After visiting Saint-Sulpice (Paris) in 1865 he returned to Turin to become rector of a Christian College of further education and technical training. This achieved a high reputation.
To make this work permanent, he founded his Congregation and promoted the Catholic Workers' Movement through the newspaper La voce dell'Operario, supported later by the monthly La buona Stampa. He also established a nationwide federation to improve the standards of the press. He died peacefully and is buried in the church of Santa Barbara, Turin. At his canonization in 1970 Pope Paul VI stressed that not only his personal virtues were honoured, but also the social activities which these virtues clothed. Feast: 30 March.
