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.
Jacob Lüroth Jacob Lüroth (18 February 1844, Mannheim, Germany – 14 September 1910, Munich, Germany) was a German mathematician who proved Lüroth's theorem and introduced Lüroth quartics. His name is sometimes written Lueroth, following the common printing convention for umlauted characters. He began his studies in astronomy at the University of Bonn, but switched to mathematics when his poor eyesight made taking astronomical observations impossible. He received his doctorate in 1865 from Heidelberg University, for a thesis on Pascal's theorem.
