CAMPBELL, Alexander Duncan. 6.1.1786 (hardly 1789) — 4.4.1857. British (Scottish) Civil Servant in India, interested in Telugu. Served in Madras Civil Service, in 1806 Collector and Magistrate in Bellary (1821 still there), 1816 Member of the Board of Superintendence for College of Fort St. George, 1827 in Tanjore, remained in India at least until 1835, when his son, the future Major-General Alexander C. was born in Madras. Later probably retired, his will is written in Middlesex. Active in Madras Literary Society. His grammar was written for the young I.C.S. recruits learning Telugu at College Fort St. George. The birth year is often given as 1789 and in this time the usual age of the arrival to India was indeed very low, but independent position as Collector and Magistrate in 1806 seems hardly acceptable.
