Heidrun Bartholomäus is a German actress and voice artist, born on July 12, 1957, in Schwerin, Germany. She trained at the prestigious Schauspielschule Ernst Busch in Berlin from 1977 to 1980, following early musical education in piano and singing. Bartholomäus has built a prolific career spanning on-screen roles in German film and television, as well as extensive work in voice-over and dubbing for international productions. In addition to performing, she is also active as a dialogue writer and dubbing director.

While Bartholomäus is widely recognized for providing the German voice for actresses such as Frances McDormand, her portfolio includes a significant body of work in anime and animated features. One of her notable anime roles is Yuzuha Tsukishiro in the fantasy series IRODUKU: The World in Colors, the German-language version of Irozuku Sekai no Ashita kara. She also voiced Kiwa in the animated film The House of the Lost on the Cape, which was released in 2021. In the 2019 anime film Children of the Sea, Bartholomäus lent her voice to the character Dede. A further credit from her earlier career is the role of Leona in the 1989 series The New Adventures of Kimba the White Lion.

Her anime and animation work extends beyond these titles. She provided the German voice for Homily in the Studio Ghibli film The Secret World of Arrietty and voiced Ginger in the animated feature Chicken Run. Another notable role includes Haruko Hoshino in the anime series Planetes.

Throughout her career, Bartholomäus has established recurring collaborations with other voice actors and dubbing studios in Germany, though these are characteristic of the industry rather than formal partnerships. Her work is regularly documented in the Deutsche Synchronkartei, the primary database for German dubbing credits. Beyond performance, her achievements include directing German dubbing for a wide array of productions, from animated films like Fritzi: A Revolutionary Tale to television series, demonstrating her comprehensive expertise in the localization process. Her consistent work as the primary German voice for acclaimed actresses like Frances McDormand highlights her standing in the profession.
