Pedro Ramón y Cajal: The Legacy of a Neurohistologist, a Medical Doctor, and a Pathologist

The work of Santiago Ramón y Cajal is difficult to understand without knowing the personalities of Justo, his father, and his brother Pedro. His father practically forced the two brothers to study medicine. Thanks to that, Santiago was able to combine his artistic talent with histology and wonderfully describe cerebral architecture. Pedro was a faithful brother and above all a friend of Santiago, and they worked together for years. Pedro was able to demonstrate the theories of his brother in nonmammalian amniotes, concluding that the basic elements of the nervous system are common to these animals and he provided images that served Santiago to formulate the theory of dynamic polarization. Pedro, who decided to remain in the shadow of his brother, was a very complete doctor, pathologist and gynecologist, who made interesting contributions in all these fields and above all was a great humanist who left an important personal and scientific legacy.
