The title 'Liberator of Indian Press' was conferred upon Charles Metcalf.
Charles Metcalf earned this honour for his significant contribution towards easing press restrictions in India.
While figures like William Bentinck were Governor-General during parts of this era, and Lord Wellesley and Lord Curzon had their own distinct policies regarding the press (often restrictive), it was Metcalf's specific actions in 1835 that directly led to this title.
Therefore, Charles Metcalf is recognized as the 'Liberator of Indian Press'.
