RESUMEN
Born in Latvia in 1836, Ernst von Bergmann received his medical education and first academic position at the University of Dorpat in Russia. In 1866, he served as a military surgeon in the Prusso-Austrian War, followed by duty in the Franco-Prussian War of 1870. He was appointed to the faculty of the University of Würzburg in 1878 and 4 years later moved to the University Clinic in Berlin. As a professor and chairman of surgery, he taught until his death in 1907. Von Bergmann practiced general surgery but devoted a large part of his career to the treatment of neurological diseases. Known for his development of aseptic technique, his early military experiences directed his attention to cranial trauma and, ultimately, neurosurgery. In 1880, he authored his first textbook, which described missile ballistics and animal experiments first demonstrating the physiological response later known as "the Cushing reflex" and advocated meticulous intracranial debridement with thorough closure after trauma. Twenty years later, as senior editor of the massive System of Practical Surgery, his contributions included pediatric neurosurgery, successful treatment of abscesses and tumors, diagnostic radiography, and cerebral localization using external landmarks and the neurological examination. Revered by his students and honored by his colleagues, von Bergmann became a proponent for aggressive neurosurgical treatment. His skilled techniques, developed in parallel with accurate experimental physiology, advanced 19th century surgical progression and formed a solid framework for the advances of neurosurgical specialists.

Born in Wetter, Germany, in 1500, Johannes Eichmann (Dryander) studied medicine and anatomy at the University of Paris from 1528 to 1534. In 1535, he was appointed professor of medicine at the University of Marburg. During the next year he held two public dissections, and in 1536 he was the author of the first text illustrating a Galenic dissection of the human brain. An expanded edition of this early book, the Anatomiae pars prior, was published in 1537. These texts represented an important transition from the dogma of medieval scholasticism to the precise observations of Vesalius. The books depicted the brain in eight figures, with four additional plates describing the skull, skull base, and cranial sutures. Detailed illustrations of the dura mater, cerebral cortex, and posterior fossa structures with clear, but inaccurate, relationship to the cranial nerves demonstrated Dryander's reliance on his own dissections. In 1542, he published a translated edition of Mundinus' anatomy. As was common at that time, the text plagiarized a portion of Vesalius' Tabulae sex, which resulted in the famous anatomist's anger. Despite this, Dryander continued to write on medical subjects as well as mathematics and astrology until his death in 1560. Because he was a progenitor of rational scientific thought, his earlier books represented an important advance in the progression to modern anatomic description and illustration.
