Few writers have dedicated themselves to their work as much as Arthur Schopenhauer, and probably none have hindered its dissemination as much as he did. If he had not encountered benevolent partners like Friedrich Arnold Brockhaus and his successors Heinrich Brockhaus and finally, in the third generation, Eduard Brockhaus, who faced the ever-new demands of their house author with almost unshakeable patience, the future of this monumental work would have been bleak. By tracing Alfred Estermann's efforts over more than four decades to achieve an adequate publication of Schopenhauer's work, he brings to light a treasure that is both amusing and culturally significant through original documents: Even though the negotiations regarding the three versions of "The World as Will and Representation" are at the forefront.
