About the author (from Wikipedia):
Robert Needham Cust (24 February 1821 – 27 October 1909) was a British administrator and judge in colonial India apart from being an Anglican evangelist and linguist. He was part of the Orientalism movement and active within the British and Foreign Bible Society. He was a prolific writer and wrote on a range of subjects.
Cust was educated at Eton College, Trinity College, Cambridge, Haileybury (1840–42) and the College of Fort William, Calcutta, graduating from the last-named institution in 1844. He then worked in the Bengal Civil Services for the East India Company, in Hoshiarpur and Ambala (assistant to the magistrate), in India.
He was present at the battles of Mudki, Ferozeshah, and Sobraon in 1845-46, where his superior Major George Broadfoot was killed and at the close of the Sikh campaign he was placed in charge of a new province in the Punjab. There he filled in succession every office in the judicial and revenue departments across Punjab, and was rapidly promoted until 1867, when he resigned and returned to England, after having been a member of the Viceroy’s Legislative Council and Home Secretary to the Government of India in 1864-65.
