Who published findings on friction skin using a microscope in Italy?

The findings on friction skin using a microscope were published by Nehemiah Grew, who conducted significant early research into the structures of human skin and the patterns found therein. His work was critical in understanding the uniqueness of friction ridge patterns, which laid the foundation for the field of fingerprinting. Grew's detailed observations contributed to the scientific understanding of skin impressions, which are now known as fingerprints.

In contrast, while Juan Vucetich is known for his contributions to the development of fingerprinting techniques and his pioneering work in police science, he did not specifically publish findings regarding friction skin under microscopic examination. Sir William Herschel was instrumental in the practical application of fingerprints for identification but did not focus on microscopic studies of skin. Johannes Purkinje, although he contributed significantly to the study of fingerprints and described various patterns, was not the first to publish findings specifically related to friction skin using a microscope. Thus, Grew stands out as the one whose research directly aligns with the question regarding microscopy and friction skin.
