Konrad Heinz von Lohengramm
From Gineipaedia, the Legend of Galactic Heroes wiki
Konrad Heinz von Lohengramm (Japanese: コンラート・ハインツ・フォン・ローエングラム) was a count and the 9th bearer of the Lohengramm name, which was a prestigious noble name dating from the time of Rudolf von Goldenbaum.
He was one of the 3 admirals that joined Marquis Rinderhof, the future Erich II, when he first rose in revolt against August II. As reward for his actions in the successful revolt, he was promoted to the rank of Fleet admiral, successively appointed to the positions of Minister of Military Affairs, Minister of Internal Affairs, Minister of State, and his noble rank was increased to marquis. This elevation in noble rank was short lived and expired after 1 generation as punishment for his second son Philip's role in the accident that led to the death of Imperial princess Magdalena.
