John Bosco, was an Italian Catholic priest, educator and writer of the 19th century, who put into practice the convictions of his religion, dedicating his life to the betterment and education of poor youngsters, and employing teaching methods based on love rather than punishment, a method that is known as the preventive system. As he was a follower of the spirituality and philosophy of Francis de Sales, Bosco dedicated his works to him when he founded the Society of St. Francis de Sales, or, popularly, the Salesian Society or the Salesians of Don Bosco. He also founded, together with Maria Domenica Mazzarello, the Institute of the Daughters of Mary Help of Christians, a religious congregation of nuns dedicated to the care and education of poor girls, and popularly known as Salesian Sisters. Bosco founded also in 1876 a movement of laity, the Salesian Cooperators, with the same educational mission to the poor. In 1875 he published a bulletin that he called Bibliofilo Cattolico - Bollettino Salesiano Mensuale (The Catholic Book Lover - Salesian Monthly Bulletin.)[4][5] The Bulletin not only has continued to be published without interruption since then, but it is currently published in 50 different editions and 30 languages. Bosco succeeded in establishing a network of organizations and centres to carry on his work. In recognition of his work with disadvantaged youth, he was canonized by Pope Pius XI in 1934.
