Early life
He was the son of Arthur Slade (1682–1746) and his wife Hannah Moore. His paternal uncle was Benjamin Slade, Master Shipwright at Deptford Dockyard.
Career outline
Like many who rose to the pinnacle of the design of British sailing warships, Thomas Slade began as a shipwright in the Royal Dockyards. His uncle Benjamin Slade was Master Shipwright at Plymouth Dockyard (a master shipwright was responsible for all ship construction and repair at the dockyard in which he served).
In 1744 Thomas became Deputy Master Shipwright at
Woolwich Dockyard

, where he remained until 5 August 1755.

He was appointed Surveyor of the Navy in August 1755 by
George Anson, First Lord of the
Admiralty, serving until his death in February 1771. For the first decade, he shared the appointment with William Bately, formerly the Deputy Surveyor of the Navy, until the latter's retirement in June 1765. On Bately's retirement, John Williams was appointed to share the post. Nevertheless, Slade was clearly the senior surveyor throughout his tenure.
He was knighted on 27 January 1768.
