Mr. Abraham Neimark

Abraham Neimark was a diamond merchant from Antwerp, Belgium.  He and his family fled to London, England when the Germans captured Belgium.  Neimark was traveling on Lusitania from New York to return to London to dispose of some diamonds and was listed as a Russian citizen.  Neimark was lost in the Lusitaniadisaster.

From the Sunday, 9 May 1915 New York Times, page 5, column 2:

Harry Niemark [sic] of Belgium anxiously awaited word of his father Abraham, who was before the German invasion a diamond merchant of Antwerp, and who had sailed for London with diamonds. Before the Lusitania left her pier he gave into the safe keeping of the purser [James McCubbin].  The elder Mr. Niemark’s [sic] family fled to London when the Germans captured Antwerp. Harry Niemark [sic] and his father came to New York three months ago, leaving their mother and sisters in London. They took rooms at 97 Division Street and a few weeks ago the father decided to return to London to dispose of the diamonds.
