Christine Wilhelmine "Minna" Planer (5 September 1809 – 25 January 1866) was a German actress and the first wife of composer Richard Wagner, to whom she was married for 30 years, although for the last 10 years they often lived apart. At an early age, she had an illegitimate daughter with a Royal Saxon Army officer, whom she raised as her sister. After a stormy courtship, which involved infidelities on both sides, she married Richard Wagner in 1836.
