A Historical, Detailed Toolmark Examination from 1916.

Marc Bischoff received his PhD from the University of Lausanne, Institute of Police Science and Criminology, and later became the head of the Institute. His final examination paper for his doctorate degree constitutes a toolmark analysis and comparison between a suspected axe and questioned cuttings of wood trunks. Bischoff uses the scientific method to test the hypothesis he formulated. Dated 1916, this report includes his notes, measurements, photomicrographs of the questioned toolmarks and the test impressions, detailed sketches, technical discussion, results, and conclusions. Recognizing the historical value of Bischoff's work, it seemed important to get it translated. Photocopies of Bischoff's original work were obtained. The case report, translated from French, is presented here along with a brief history of the Firearm and Toolmark Identification field and Bischoff's role in the beginning of this field. Bischoff's work stands as testimony to the long tradition of the field of forensic toolmark analysis. [ABSTRACT FROM AUTHOR]
