Antonia Feuerstein, the German singer, actress and daughter of television star Jutta Speidel, has attracted renewed public attention following a joint appearance with her mother on the ARD quiz show Quizduell-Olymp. The 40-year-old performer joined Speidel for the televised competition, where they discussed their family relationship and competed for a charitable cause.
Feuerstein, who also uses the professional name Antonia Speidel, has built a career in classical music, acting and voice training. Although she comes from a well-known German entertainment family, much of her professional work has taken place outside mainstream television.
Antonia Feuerstein and Jutta Speidel Appear on Quizduell-Olymp
Antonia Feuerstein and her mother appeared on Quizduell-Olymp on October 30, 2026. The programme, presented by Esther Sedlaczek, featured the mother and daughter answering questions against the show’s regular quiz experts.
During the programme, Feuerstein discussed her relationship with her mother. She acknowledged that, like other families, they experience both good and difficult days.
The pair did not win the final round. However, their appearance secured €1,000 for Horizont e.V., the Munich-based charitable organisation founded by Speidel in 1997 to support homeless mothers and children.
The television appearance brought renewed attention to Feuerstein’s professional background and her relationship with one of Germany’s established television actresses.
Who Is Antonia Feuerstein?
Antonia Feuerstein was born in 1986 and is the daughter of German actress Jutta Speidel and businessman Stefan Feuerstein. She is 40 years old in 2026.
Her mother is known for her work in German television productions, including Um Himmels Willen, Forsthaus Falkenau and Alle meine Töchter.
Feuerstein grew up in a family connected to the entertainment industry. She has an older sister, Franziska, who has maintained a comparatively private life.
In March 2024, Feuerstein accompanied her mother to an event promoting Speidel’s novel Amaryllis. During an interview, she discussed the challenges of growing up with a successful actress as her mother.
Feuerstein explained that establishing her own professional identity had taken time, although she remained grateful for her family.
Antonia Feuerstein’s Acting Career
Feuerstein began appearing in German television productions during the early 2000s.
Her screen credits include the 2001 television film Ein Stück vom Glück, in which she portrayed Miriam Below. The production also featured Jutta Speidel and Wolfgang Stumph.
In 2002, she appeared as Bettina Roll in the German television series Um Himmels Willen, internationally known as For Heaven’s Sake.
She later played Mia in the 2013 television production Inga Lindström: Das Geheimnis von Gripsholm, directed by Dennis Satin.
Although Feuerstein has several documented acting credits, she subsequently developed a professional career centred primarily on music and voice-related work.
Music Education and Professional Career
Feuerstein studied classical singing and developed her skills in opera and concert performance. Her musical education included studies at the Hochschule für Musik Detmold.
She has also worked as a singer, speaker and voice trainer. Her professional activities have included musical performances and projects combining spoken literature with classical music.
Alongside her artistic career, Feuerstein expanded her qualifications into Pilates instruction and nutritional counselling.
Her work now covers several areas, including singing instruction, speech training, physical movement and nutrition.
What Is Antonia Feuerstein Doing Now?
Feuerstein continues to work across music, voice coaching and wellness-related training. Her professional activities differ from the television acting career that made her mother widely recognised.
Her October 30 appearance on Quizduell-Olymp placed her alongside Jutta Speidel in a nationally televised programme.
The mother and daughter’s participation also supported Horizont e.V., continuing the family’s association with the Munich charity.
