"Sir Thomas Rumbold, 1st Baronet (15 January 1736 – 11 November 1791) was a British administrator in India and politician who sat in the House of Commons between 1770 and 1790. He served as Governor of Madras from 1777 to 1780. He became infamous for his corruption and, for in effect stealing, the ring of the Nawab of Arcot. He brought home from India 1.5 million pagodas (a pagoda was worth eight shillings) or about £600,000 (at that time) and was a classic example of a nabob. Attempts were made to investigate the misdemeanour by Henry Dundas but the case did not make much headway." - (en.wikipedia.org 12.08.2021)
