The historian and archivist of the House of Württemberg, Eberhard Fritz, believes that Claus von Stauffenberg's opposition to Adolf Hitler may have been partly motivated by his relationship with the House of Württemberg. (Stauffenberg's father was the last Oberhofmarschall of the Kingdom of Württemberg). Stauffenberg was personally acquainted with Father Odo and was well aware of pockets of resistance against the Nazis.[3]
