Read the full account

In 1887 Edison established a larger laboratory and manufacturing complex at West Orange, New Jersey, succeeding Menlo Park as his principal works. The National Park Service now preserves the site.

Context

Phonograph manufacture, ore milling experiments, and later motion pictures used the same campus. Labour, fire, and management are later Facts.

Thomas Edison 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

High confidence on the site.

A campus is not a patent. Keep products on their own rows.

Who was responsible

Contribution type and responsibility level for each recorded actor — not sole-author shorthand.
