The quarantine station — where the voyage stopped short of Philadelphia

The nineteenth century’s great crossing

At the end of the nineteenth century large numbers of people left Europe for America to escape poor economic conditions. They travelled in conditions that were crowded by design, on ships that had every incentive to fill the steerage deck, and they carried with them whatever was circulating in the ports they left from — cholera, typhus, smallpox, bubonic plague.

Philadelphia was a major destination, and everything bound for Philadelphia comes past Cape Henlopen. That geography made Lewes the natural place to intercept a ship before it reached the city, in exactly the way it made Lewes the place to stop a British squadron or a German fleet.

What a quarantine station did

A quarantine station is a filter and a holding pen. Arriving vessels were boarded and inspected; the healthy could proceed, the sick were detained, and the ship itself might be held and fumigated. The word “quarantine” comes from the Venetian quaranta giorni, forty days, the period plague ships were once made to wait — though by the nineteenth century the periods were shorter and tied to specific diseases.

It is worth being clear about what this meant for a passenger. After weeks at sea, within sight of the American shore, an emigrant family could be taken off the ship and held on an island or in a station building, sometimes for weeks, sometimes separated from each other, occasionally to die there. The station existed to protect the city; it was experienced as one more ordeal at the end of the crossing.

Quarantine was also, everywhere it operated, entangled with prejudice. Which ships were inspected most rigorously, which nationalities were assumed to be diseased, and which passengers were detained were not purely medical judgements. Public health and nativism ran together throughout this period, and any honest account of a quarantine station has to hold both.

Why it is hard to see now

This station has left far less trace in the public record than Ellis Island or Philadelphia’s Lazaretto, and we were not able to find independent documentation of its buildings, dates of operation or closure to set beside Mr. Ippolito’s article. It is one of the genuine gaps in this archive.

That is itself informative. Facilities like this one were unglamorous, administratively boring and associated with people whose arrival was not celebrated, so they were poorly recorded, rarely photographed and readily demolished. If you hold records, photographs or family memory relating to the Delaware Breakwater quarantine station, we would be glad to hear from you and would credit the contribution.

From the original page at this address

“At the end of the 19th century thousands of immigrants fled poor economic conditions in Europe by emigrating to America. In addition to their dreams of a brighter future, many of these newcomers also carried with them a variety of epidemic diseases including cholera, typhus, smallpox and bubonic plague.”
