Mendel Rosenberg emigrated from Germany to New York in early 1947, with a surviving embarkation card dated 27 February 1947 and arrival in March 1947.

Evidence

The St. Louis Holocaust Museum page links a document explicitly labeled 'Mendel's Embarkation Card 2-27-1947' and a separate 'Bremen Passenger Ticket.' The supplied GEDCOM places Mendel and Recha in adjacent entries in both the DP passenger collection (1,61704::80403 and ::80402) and the New York passenger collection (1,7488::3037698361 and ::3037698360), strongly supporting joint travel. An independent contemporary travel-diary chronology for another passenger records boarding SS Marine Flasher at Bremerhaven on 28 February 1947, arrival at New York on 13 March, and overnight quarantine before harbor entry on 14 March. JDC's archival file 1199 confirms that its Marine Flasher 1946-1948 holdings contain passenger lists. This voyage fits the Rosenbergs' indexed 27 February departure and 13/14 March arrival unusually well, but no Rosenberg manifest row or JDC passenger-list row has yet been directly inspected; those context sources are therefore not treated as direct support for the person-specific claim.

What remains uncertain

SS Marine Flasher is now the strongest ship hypothesis but is not yet confirmed for Mendel and Recha. Bremen likely reflects processing/administrative geography while Bremerhaven was the physical seaport for the matching voyage; Mendel's later memory of boarding at Hamburg remains unsupported by contemporary Rosenberg paperwork. The 13 versus 14 March arrival dates can plausibly reflect anchoring versus post-quarantine harbor entry, but person-specific passenger evidence is still required before treating that interpretation as established.
