| | Friedrich Nietzsche |
 | | He witnessed the traumatic effects of battle, took close care of wounded soldiers, contracted diphtheria and dysentery, and subsequently experienced a painful variety of health difficulties for the rest of his life. |
 | | From 1880 until his collapse in January 1889, Nietzsche led a wandering, gypsy-like existence as a "stateless" person (having given up his German citizenship, and not having acquired Swiss citizenship), circling almost annually between his mother's house in Naumburg and various French, Swiss, German and Italian cities. |
 | | On the morning of January 3, 1889, while in Turin, Nietzsche experienced a mental breakdown which left him an invalid for the rest of his life. |
