Sir Thomas Spert was Master of Trinity House for 27 years. After his death the constitution was changed, with all Elders or Masters holding their positions for only three years. After this time they had to stand down or be re-elected by the Trinity Court of Brethren.
He is said to have lived in a 14th-century wooden manor house at Coldharbour in Blackwall. The house was still standing in 1881 when it was 152 East India Dock Road.
