Peter Groeger was a distinguished German actor and voice artist, born on June 1, 1933, in Gröbzig, Germany, who passed away on January 16, 2018, in Berlin. His career was deeply rooted in the performing arts, beginning with his education at the Ernst Busch Academy of Dramatic Art in Berlin and continuing with studies in direction at the prestigious GITIS institute in Moscow. He worked extensively as a stage actor and director, holding significant positions such as Head of International Radio Drama at the GDR radio broadcast service, which established his long-standing connection to audio drama and voice work.

While Groeger's voice is widely recognized for dubbing the character Quark in the German version of Star Trek: Deep Space Nine, his contribution to the world of anime through German dubbing is remarkably extensive. He was the German voice for a vast array of characters across many notable films and series. He lent his voice to the character Herr Rossi in the series Romeo and the Black Brothers, Alexandro Pecchino in the film King of Thorn, Mabarowa in Oblivion Island: Haruka and the Magic Mirror, Don Alejandro de la Vega in Kaiketsu Zorro, and Totto in The New Adventures of Kimba The White Lion. His filmography also includes the role of Dr. Onishi in the first German dub of Akira, the Grand Master in The Boy and The Beast, Dakuan in Ninja Scroll, and Shouan in Sword of the Stranger.

Groeger was a prolific presence in German-dubbed anime, taking on roles that ranged from wise elders to cunning villains. He voiced Solomon Muto in Yu-Gi-Oh!, Watari in the live-action Death Note films, and Gabal Docker in Gurren Lagann. His work extended to numerous other titles, including Skalle-Per in Ronja the Robber's Daughter, Inbe no Akita in The Tale of the Princess Kaguya, and Elder Urakuo Hakubi in ID-0. He was also heard in popular series such as One Piece, Bleach, and Detective Conan.

Beyond his on-screen voice work, Groeger was celebrated for his radio dramas, most notably as the voice of Dr. Watson in a long-running German Sherlock Holmes series, and for his performances at the Berlin Criminal Theatre. His extensive and versatile body of work made him a familiar and respected voice in German entertainment for decades.
