Rt. Rev. Mgr. Daniel Murphy, at the age of 30, became the first Vicar Apostolic of Hyderabad during the 18th year of the reign of the Fourth Nizam, Asaf Nasirud Dowla Bahadur. Two years prior to the Great Indian Mutiny, on the 11th day of June, in the year 1855, he founded a school at the request of his Highness and named it College of All Hallows after his Alma Mater in Ireland. It was then at Maretts Bunglow at Basheerbagh and educated only the English and the Anglo-Indian students of His Highness, the Nizams army staff. Three years after, he persuaded the Superior General of Milan Foreign Mission Society to adopt the College of All Hallows and six years after that he left for Ireland owing to his ill-health.
