Throughout all of his famous papers on 1905, Einstein gives no sources or citations. The only credit given to anyone is a brief mention of his friend Michele Besso. Why the lack of citation of any source material? Interestingly, Besso was originally from the Veneto region of Italy; his native tongue was Italian. The city of Vicenza, Italy, again in the Veneto region, was where Olinto De Pretto was from. Michele Besso was close to his uncle, Beniamino Besso, who lived in Rome. Beniamo Besso worked as an engineer in Rome with Olinto De Pretto's brother, Augusto De Pretto. Perhaps Augusto passed on Olinto's discovery to Beniamo Besso who in turned told Michele Besso who in turn told Einstein—or so goes the thread.
