Which person that Roger Manvell made a biography of had the middle name of Luitpold?
Heinrich Himmler Heinrich Luitpold Himmler (] ; 7 October 1900 – 23 May 1945) was "Reichsführer" of the "Schutzstaffel" (Protection Squadron; SS), and a leading member of the Nazi Party (NSDAP) of Germany. Nazi leader Adolf Hitler briefly appointed him a military commander and later Commander of the Replacement (Home) Army and General Plenipotentiary for the administration of the entire Third Reich ("Generalbevollmächtigter für die Verwaltung"). Himmler was one of the most powerful men in Nazi Germany and one of the people most directly responsible for the Holocaust.
Ludwig Windthorst Baron Ludwig Windthorst (17 January 1812 – 14 March 1891), was a German politician and leader of the Catholic Centre Party, the most notable opponent of Chancellor Otto von Bismarck during the Prussian-led unification of Germany and the Kulturkampf. Anderson argues that he was "Imperial Germany's greatest parliamentarian," one who bears comparison with Irishmen Daniel O'Connell and Charles Stewart Parnell "in his handling of party machinery and his relation to the masses."
