In 1900, at the age of nineteen, she married Baron Heinrich Georg Ludwig von Puttkamer, a member of the Pomeranian nobility who was 35 years her senior.
[3] Upon her marriage, Baroness von Puttkamer moved into a villa with her husband in Grunewald, Berlin and frequently traveled to Vienna, Paris, Nice, and Monte Carlo where she socialized with Hollywood actors, European royalty and nobility, artists, and writers and began using morphine recreationally.
[4] In her novella Morphium, von Puttkamer describes how her morphine use began in 1914 when a doctor injected her with the drug to quiet her uncontrollable grief at her husband's deathbed.
[4] In 2016, Baroness von Puttkamer's rediscovered works were translated into English and compiled into the book Priestess of Morphine: The Lost Writings of Marie-Madeleine in the Time of Nazis by Ronald K.
[4][14] An operatic monodrama about von Puttkamer's life, The Priestess of Morphine: A Forensic Study of Marie-Madeleine in the Time of the Nazis, was created and recorded by composer Rosśa Crean and writer Aiden K.
