At Ellis Island, peak processing reached 1,004,756 immigrants in 1907 and some days topped 12,000 people in a nonstop rhythm of medical and administrative decisions. Even the smallest details, from staff calling the next name to the sulfuric acid used to protect the station’s infrastructure, can be traced in digitized records and photo collections today. What’s striking is how this single 27 acre site generated more than 25 million passenger record entries, linking manifests, detention notes, and naturalization indexes into one searchable trail.
