Army officer and writer. He served in the army of the East India Company, rising to the rank of Major. After retiring back to his home county of Suffolk due to ill health, he produced the Hindu Pantheon (1810), which for over fifty years was the only authoritative book in English on the subject, and thus widely consulted. Other publications included Hindu Infanticide: an Account of the Measures Adopted for Suppressing the Practice (1811), Oriental Fragments (1834), and Suffolk Words and Phrases (1823). He was a founding member of the Royal Asiatic Society and was elected to membership of the Asiatic Society of Bengal (1796), the Royal Society (1806), and the Society of Antiquaries (1818). Moor was on good terms with Bernard Barton and Thomas Clarkson, both part of Southey’s extended circle. He corresponded with Southey in the late 1810s and early 1820s, offering him the use of the papers of his brother-in-law, Sir Augustus Simon Frazer (1776–1835; DNB), to help with Southey’s History of the Peninsular War (1823–1832).
