 The company of seven was led by historian Friedrich Christoph Dahlmann, who himself was one of the key advocates of the unadulterated constitution.The other six were the Germanist brothers Wilhelm and Jacob Grimm (famed fairy tale and folk tale writers and storytellers, known together as the Brothers Grimm), jurist Wilhelm Eduard Albrecht, historian Georg Gottfried Gervinus, physicist Wilhelm Eduard Weber, and theologian and orientalist Heinrich Georg August Ewald.The constitution that Ernest Augustus opposed came into effect in 1833, while he was still heir presumptive to the Hanoverian throne.
