    Sir Francis Galton was a great fingerprint pioneer as well as a man of considerable talent in many other areas. S. Early Fingerprint Usage in Other Countries Germany From the first thesis by Hintz in 1747, in which spiral shapes on the skin of the hands and feet were discussed, numerous German researchers noted papillary ridges, including Schroeter, Huschke, Welker, Kollman, and Eber. In 1902, while studying law in Munich, Robert Heindl (1883–1958) read in an English magazine about the use of a fingerprint classification system and wrote to India for details.

    2 All training programs for latent print examiners place great emphasis on practical experience during the phases of instruction regarding the evaluation and comparison of latent prints. This emphasis is well founded and has considerable merit, but it has been stressed so heavily that little written information exists regarding the methodologies and procedures for making a comparison of two prints. This lack of information has resulted in a failure to adequately define the many tasks involved in the evaluation and identification processes and the subsequent failure of many persons to recognize the scientific nature of latent print identification.
