drafts and inserted changes for On War in a manner of months. Later years and death Toward the end of her life, Brühl complained of tightness in her chest and ringing in her ears. She lived a busy life with an irregular and hectic schedule. Along with her responsibilities as chief lady-in-waiting, von Brühl also put pressure on herself to publish her deceased husband's works. Those around her were concerned about her health, mood swings, and frequent restlessness. Marie suffered a psychological breakdown after an intense fight with her mother. After the episode, doctors prescribed various treatments and medications including, "bloodletting, laxatives, and nauseant." These seemed to be making Marie sicker and less lucid; she sometimes even spoke of herself in the third person. Her cousin Carl von Brühl insisted on moving her to Dresden to salvage what was left of her health. According to one of her nurses, Marie's arm seemed to have become infected due to the practice of bloodletting. She may have also contracted hepatitis from the bloodletting instruments. Due to the lack of knowledge about modern medicine and infections, the doctor in Dresden simply diagnosed Marie with damaged nerves and ceased treatment. On January 28, 1836, Brühl died at the age of 56. Family Her paternal grandfather was Heinrich von Brühl, a Polish-Saxon statesman. Legacy Her portrait of Prussian Field marshal August Neidhardt von Gneisenau is in the collection of Deutsches Historisches Museum.
