Hans Heinrich Georg Queckenstedt

Hans Heinrich Georg Queckenstedt (1876 in Leipzig-Reudnitz – 9 November 1918 in Harburg, Prussia) was a German neurologist remembered for describing Queckenstedt's phenomenon. He graduated from the University of Leipzig in 1900, having studied under Emil Kraepelin. He worked under Sigbert Josef Maria Ganser, and gained his doctorate in 1904. He worked in Rostock, and was habilitated as Privatdozent in 1913. He studied cerebrospinal fluid dynamics, noting the fluctuation of pressure with respiration. This led to experiments with the Valsalva manoeuvre and jugular vein pressure from which his eponymous test was published. During the First World War he was head of the army medical service in Harburg; he was thrown from a horse and killed by a passing truck two days before Armistice Day.
