Sir Thomas Chaloner the Younger, of Steeple Claydon (chemist and courtier) was born in 1561. He was a distinguished naturalist and was selected by James I. to superintend the education of his son, Prince Henry, Prince of Wales. For his services he was presented with the sum of £4,000, as a free gift. On visiting Rome at the end of the 16th century he noticed that the discolouring of leaves on trees near the Pope's alum works resembled those near his own home in Guisborough. He also realised the clay of both regions was similar too. He returned from Rome with much Papal anger, and with some key Italian workers, who knew all the processes of alum manufacture. His competitive edge was effective. The Pope had been exporting alum to England at £52 for a ton. But the new supply was a mere £11 per ton. The Pope issued a curse on Chaloner and excommunicated him. When Charles became King he confiscated much of their estate because of the alum mined there and set up a syndicate for distributing its wealth, thus giving Sir Thomas's sons reason for revenge years later at the King's trial. He died in 1615. He married Elizabeth Fleetwood.
