Hans Heinrich Georg Queckenstedt, whose communication on the significance of the interruption of the free flow of cerebrospinal fluid led to eponymic identification, was born in Leipsig-Reudnitz into a schoolteacher's family of limited means.1 His intellectual capacity, recognized in his early youth, was expressed in an attraction to physics, mathematics, and the natural sciences. Upon completion of his medical education at the University of Leipzig, and passing the state examination in 1900, Queckenstedt entered the service of Prof S.J.M. Ganser in the Municipal Hospital in Zwickau, known at that time as the Dresden Hospital for Mental Diseases. In 1904, the MD degree was awarded, upon presentation of an inaugural dissertation on carcinosarcoma to the medical faculty of Leipzig.
Queckenstedt, an excellent clinician, devoted most of his energies to the management of the sick, first in the medical polyclinic in Heidelberg and later at the medical clinic in Rostock. Subsequently
