Actually, Eves deLage was a French anatomist who, in 1902, studied the first photographs of the shroud taken by Secundo Pio in 1898. DeLage was an agnostic who did not believe in miracles, but he did believe, based on his analysis, that the shroud was the authentic burial cloth of Jesus. He did not believe that the image formation was supernatural, but by a natural process of vapors emanating from the corpse.
