In July 1966 Schneider married Harry Meyen (1924–1979), a German director and actor who committed suicide in Hamburg, Germany in 1979. The couple had a son, David Christopher, born on December 3, 1966. David died at the age of 14 on 5 July 1981. He had attempted to climb the spiked fence at his stepfather’s parents’ home when he punctured his femoral artery.
Schneider began drinking alcohol in excess after the death of her son David. When she was found dead in her apartment in Paris on 29 May 1982, it was suggested that she had committed suicide by taking a lethal cocktail of alcohol and sleeping pills. After another post-mortem examination was carried out, authorities declared that she had died from cardiac arrest. Her tombstone at Boissy-sans-Avoir in the Canton of Montfort-l’Amaury bears the name Rosemarie Albach. Shortly afterwards, Alain Delon arranged for David to be buried in the same grave
