In 1894 a translation of Kayserling's book on Christopher Columbus and Spanish Jews was published--- "Christopher Columbus and the Participation of the Jews in the Spanish and Portuguese Discoveries" (translated by Charles Gross [1857-1909]).
The curious relationship which Columbus' discovery has with the Jews in Portugal and Spain, is the subject of this book. As Kayserling notes there is some evidence that Columbus himself was of Spanish-Jewish origins; Kayseling gives a full review of this evidence. The forced contributions of the Jews, historians have made note of before this, but Dr. Kayserling, who has carefully studied the records in Spain, produces much new evidence relating to individual Jews, who by their teachings or personal exertions were of singular help to Columbus. The work is distinguished for its impartiality.
"FEW mortals have been honored by posterity as much as Christopher Columbus. The question whether the Jews assisted in these discoveries has already heretofore been propounded, but it has never before been carefully investigated. Entrusted with this honorable but difficult mission, I determined to visit Spain in order to complete my collection of material by exploring the Spanish archives and libraries. Such documents as I found there, I transcribed. They have been used with care in the text. I trust that I have succeeded in making a contribution to the history of the discovery of America and to the history of the Jews, to whom America has been a land of refuge, a land of freedom and of equality."
