Book excerpt: "A visionary and a madman" was how one British statesman, Lord Carteret, described Theodore von Neuhoff. This exciting biography, Theodore von Neuhoff, King of Corsica: The Man behind the Legend by Julia Gasper, traces the unlikely career of the German baron who in 1736 had himself crowned the King of Corsica. Theodore von Neuhoff's career spanned the entire European continent and his role in the Corsican rebellion against Genoa was as bold and unconventional as everything else in his life. Mixing with royalty, rogues and rabble, he was successively a soldier, secret agent, Jacobite, speculator, alchemist, cabbalist, Rosicrucian, astrologer, fraudster, and spy. He had changed his name several times, abducted a nun and seen the inside of several prisons before turning his hand to revolution. Neuhoff had daring far-sighted ideas about religious tolerance and the abolition of slavery that turned the Corsican rebellion into a significant political event with repercussions way beyond the shores of one small island. Denounced as an arch-criminal, traitor and seditious heretic, he survived pursuit by the agents of the Genoese Republic for twenty years with a price on his head, dodging assassination attempts while meeting countless famous and fascinating people. Valuable to the British as a political tool against the French, he spent his old age in relative comfort in an English debtors' prison. Theodore von Neuhoff, King of Corsica argues that despite all his eccentricity Neuhoff was still a significant Enlightenment figure.
