Benjamin Ehrlich’s The Brain in Search of Itself is the first major biography in English of this singular figure, whose scientific odyssey mirrored the rocky journey of his beloved homeland of Spain into the twentieth century. Born into relative poverty in a mountaintop hamlet, Cajal was an enterprising and unruly child whose ambitions were both nurtured and thwarted by his father, a country doctor with a flinty disposition. A portrait of a nation as well a biography, The Brain in Search of Itself follows Cajal from the hinterlands to Barcelona and Madrid, where he became an illustrious figure―resisting and ultimately transforming the rigid hierarchies and underdeveloped science that surrounded him. To momentous effect, Cajal devised a theory that was as controversial in his own time as it is universal in ours: that the nervous system is comprised of individual cells with distinctive roles, just like any other organ in the body. In one of the greatest scientific rivalries in history, he argued his case against Camillo Golgi and prevailed.
