An Oriental Biographical Dictionary (original title The Oriental Biographical Dictionary) was an important biographical dictionary of the Islamic, Persian and Indian worlds by Thomas William Beale, published posthumously by The Asiatic Society of Bengal in 1881. A new edition, revised and enlarged, was published in London by W. H. Allen in 1894. The book has since been reprinted several times and is now out of copyright. Both editions were edited by Henry Keene, Fellow of the University of Calcutta and a contributor to the Dictionary of National Biography.
Little is known of Beale, other than that he was a clerk in the office of the Board of Revenue of the North West Provinces and evidently a knowledgeable amateur historian. According to Keene's preface to the 1894 edition of the work, Beale had never been in Europe and died at an advanced age in Agra, 1875.[1] He was also the author of a historical work in Persian, Persian: مفتاح التواريخ , published in 1867.
