There is not alot of info about Thomas Haye on the internet unfortunately. Here is what I do know:
Haye flourished between 1690 to 1720. He was a member of the Founders' Corporation, although no details of his career within it are known.
Along with the Royal Clockmaker, Jérôme Martinot, Haye built a mechanised armillary planetarium that was presented to Louis XIV in February 1701.
Haye is chiefly known for his sun-dials, and authored a noteworthy book on the subject. A link is provided below, along with a pics of the Title Page and an instrument that looks a good deal like the backside of the Haye Compendium I have offered for sale. Haye apparently also made a fair number of surveying instruments, as I have found a Graphometer, a surveyor's compass, a plane table compass and my compendium.
A famous researcher and writer on Scientific Instruments (Anthony Turner) published a blurb in a 2014 book about Thomas Haye. I haven't found the book yet but am still trying to track one down. I suspect Turner's blurb has everything that is findable relating to Thomas Haye. The cite is:
Anthony Turner, ‘Thomas Haye: an early Eighteenth Century Paris instrument-maker’ in Marvin Bolt, Lauren Boegen, Bruce Stephenson & Teasel Muir-Harmony (eds), Rod and Madge Webster, a Legacy of Collections, Philanthropy and Friendship, Chicago 2014, 134-41.
