“…A 1929 protein chemistry book defined syntonines (plural) as products obtained by the action of acids….on proteins. 25 Sander's work in this area did not fundamentally alter our understanding (or misunderstanding) of syntonin.…”

Zitterbewegungen des Fusses bei Dorsalflexion (shaking movements of the foot upon dorsal flexion) were observed independently from each other and described in the same issue of a German peer reviewed journal by Carl Westphal (1833–1890) at the Charité in Berlin and by Wilhelm Erb (1840–1921) in Heidelberg. While Westphal used the term Fussphaenomen, Erb is credited with coining the term clonus for the phenomenon. Both scientists are immortalized by various eponyms acknowledging their respective contributions to science. Little is known however about Julius Sander (1840–1909), in those days resident at Charité, who noticed the phenomenon and presented it to his superiors, Wilhelm Griesinger (1817 −1868) and Westphal. In addition to such observations, Sander made original contributions in resuscitation physiology while working with Hugo Kronecker (1839–1914). With Kronecker, Sander published observations on life saving transfusions with inorganic salt solutions in dogs “ Bemerkung über lebensrettende Transfusion mit anorganischer Salzlösung bei Hunden” a very early work on isovolemic fluid resuscitation. The purpose of this communication is to highlight Sander's scientific contributions and to shed some light on his life, of which a German Lexicon stated that after 1870 no information on him can be ascertained anymore.

“…Most inorganic elements are only present as trace, incidental impurities in human hair, so early applications of mass spectrometry to human hair focused on the detection of the most abundant elements. In the 1930s, many scientists evaluated the levels of iron in human hair relative to different traits using chemical extraction and wet chemical techniques. − In the 1950s and early 1960s, spectroscopic methods like flame atomic absorption (FAA) enabled the detection of the most abundant metals like iron and copper and even mercury and lead exposure in cases of poisoning. − By the 1960s, neutron activation analysis (NAA) achieved new levels of detection for the few elements that were amenable to NAA . In 1969, J. P. Yurachek et al analyzed 22 elements in human hair in a single analysis using SSMS .…”

Mass spectrometry has made profound contributions to the criminal justice system by providing an instrumental method of analysis that delivers exquisite analytical figures of merit for a wide variety of samples and analytes. Applications include the characterization of trace metal impurities in hair and glass to the identification of drugs, explosives, polymers, and ignitable liquids. This review describes major historical developments and, where possible, relates the developed capabilities to casework and legal precedents. This review also provides insight into how historical applications have evolved into, and out of, modern consensus standards. Unlike many pattern-based techniques and physical-matching methods, mass spectrometry has strong scientific foundations and a long history of successful applications that have made it one of the most reliable and respected sources of scientific evidence in criminal and civil cases. That said, in several appellate decisions in which mass spectrometric evidence was challenged but admitted, decisions sometimes still went against the mass spectrometric data anyway, which goes to show that mass spectrometric evidence is always just one piece of the larger legal puzzle.
