The industrialist Olinto De Pretto, a native of the Veneto region of Italy, published the article in which he gave, in its final form, the equation E=mc2. This article appeared on June 16, 1903, and was published again in February 27, 1904, the second time in the Atti of the Reale Instituto Veneto di Scienze. De Pretto thereby preceded Einstein's famous 1905 " E=mc2 " paper by at least a year-and-a-half. In the article, Olinto De Pretto actually comments on how amazing his discovery is. De Pretto could hardly believe his mathematical discovery.
