Maria Anna Sabina (von) Genzinger (6 November 1754[1] – 26 January 1793), called Marianne, was a Viennese amateur musician, the mother of six children, and a friend of the composer Joseph Haydn. Her correspondence with Haydn preserves a personal view of the composer not available from any other biographical source.[2] Her daughter Josepa was a singer who gave the first performance of Haydn's Ariadne auf Naxos.[3]
