Before the invention of photocopiers and electronic text storage, a writer's work had to be stored on paper, which meant it was very susceptible to fire in particular. (In very earlier times, writers used vellum and clay which were more robust materials.) Writers whose work was destroyed before completion include L. L. Zamenhof, the inventor of Esperanto, whose years of work were thrown into the fire by his father because he was afraid that "his son would be thought a
