McCrone is most widely known for his work with the


Shroud of Turin and the Vinland Map. In 1978, he con- cluded that the Turin Shroud is a medieval painting; his findings were later solidified by radioactive carbon-14 dating techniques. In 1974, he was the first to conclude and publish that the Vinland Map was a post-1920s forgery, aſter using polarized light microscopy to discover an early version of the man-made pigment anatase on it. Debated for decades, his Vinland Map findings by microscopy 48 years ago were confirmed by Raman spectroscopy in 2002 and again in 2021. In 2000, McCrone received the American Chemical


Society National Award in Analytical Chemistry for his work on the Turin Shroud and for his enduring patience for the defense of his methodologies. McCrone’s career was remarkable in many ways. His


pioneering efforts were highlighted by many honors and awards. He is honored for his humanitarian efforts with Ada S. McKinley Community Services in Chicago by the dedication of a facility that bears his name. Dr. McCrone is not only a microscopy pioneer, but also an example of how to live fully and give generously.
