Later hospital and Confessions readers treat the Enfants-Trouvés deposits as an infectious-crowding fact
The dated public pairing used here is the 1782 admission plus later public-hospital memory of that crowding. In the causal graph this event strengthens Infectious-Disease Transmission, a driver that weakens Life expectancy at birth — a worsening welfare path.

Read the full account
Eighteenth-century foundling wards were crowding machines for measles, smallpox, and enteric disease. The dated public pairing used here is the 1782 admission plus later public-hospital memory of that crowding. He did not design the ward.
Context
This is not a unique bacteriology paper. It is a transmission-path reading of a documented deposit into a crowded institution. Medium confidence.
Jean-Jacques Rousseau is not the sole author of every later object, law, or museum label that uses the name. Shared work with courts, excavators, printers, spouses, officials, and later states does not erase a documented role, and it does not make an ancient person the signer of a twentieth-century statute.
Why it matters
A crowded foundling ward is an infection path, not a 1747 death certificate for each child.
