St John Bosco, or Don Bosco, is an Italian educator and saint who followed the spirituality and philosophy of St Francis de Sales and founded the Salesians of Don Bosco, a community of Catholic priests and brothers.
He dedicated his life's work to the education of street children, juvenile delinquents and disadvantaged youth, using a method of love rather than punishment known as the Salesian Preventive System using “reason, religion and loving-kindness”.
Together with Maria Domenica Mazzarello, he founded the Institute of the Daughters of Mary Help of Christians, a religious congregation of nuns dedicated to the care and education of poor girls.
In the late 1800s he also founded a lay movement to bring education to the poor. This movement, together with religious men and women belong to the Salesian family, dedicated to the service of children and youth.
