“Perkins Elmer - Danbury — 1967”
Declassified records show the Wooster Heights facility was under construction in 1967 for the HEXAGON reconnaissance program.
Perhaps the archive's best example of a mundane contractor notation concealing extraordinary national history — with a declassified brick-veneer anecdote that is almost tailor-made for a masonry archive.
What Kelly did here
Family source
Strong
Concrete-block masonry walls and partitions are the strongest material match. The planned brick veneer should NOT be attributed to Kelly because declassified records say it was ultimately omitted.
This scope is recorded as strong, not documented. It is a disciplined reading of the building and the trade practice of the period, not a contract-level record of Kelly’s work.
