She was born
Marianne Helene Sara Kahn in
Mannheim, Germany on 23 June 1890. She was baptised as a Lutheran in 1896, though her father's family were Jewish. In 1913, Marianne married Colonel Erich Mathy, an officer of
Kaiser Wilhelm II's Imperial German Army. Though they divorced the next year, with Eric killed in action shortly thereafter, Marianne retained Mathy's name for the remainder of her life. In 1921, she married Berlin architect, Franz (Francis) Martin Friendenstein. They later changed this name by deed poll in February 1945 from Friendenstein to Frisdane. Her musical education included piano, theory, speech training, interpretation and voice production, with a special course for the treatment of damaged vocal cords. Though her initial formal training emphasised piano, Marianne showed early promise as an opera and classical singer. In 1918 Marianne was offered her first engagement singing at a provincial opera, as Gretel in
Engelbert Humperdinck's
Hansel and Gretel. She became well known as an interpreter of
Lieder and of early music. She went on to perform in Germany during the 1920s and 1930s. In 1929, Mathy received the State Certificate, Berlin, with Honourable Mention in recognition of her public performances and as a teacher of singing. ==Australia==
