Henry Cort was connected to the navy in many ways.
His early work was as a navy agent.
One of his clients was Lieutenant John Becher, whose sister-in-law he married.
When he took over the Attwick ironmongery business, his main customer was the Navy.
He undertook work on hoops for the Navy, and submitted the product of his fining process to them for testing.
Much of the finance for his business came (unfortunately!) from navy clerk Adam Jellicoe.
Research into Cort necessarily involves looking at navy records.† Some topics investigated turned out to have little relevance to Cort, but are still of historical interest.
