I have not gotten far on my research. Not much out there that I can find plus I have been fairly busy with work and my seminary studies. I only really know that Isaac learned his trade in Amsterdam, moved to London and then New York. Googling Jewish Cigar Makers brought up the following links:http://knowlescollection.blogspot.com/2010/09/cigar-makers-o...http://jewishcurrents.org/wp-content/uploads/2010/02/Jews-Am...
There may also be a book linked to the labor movement: Jewish Workers and the Labour Movement: A Comparative Study of Amsterdam, London and Paris, 1870-1914
Of course there is Samuel Gompers: http://www.jewishvirtuallibrary.org/jsource/biography/gomper...
Hope this helps! Anything you find out I would be interested in learning.
