Günther "Guy" Stern (January 14, 1922 – December 7, 2023) was a German-American decorated member of the secret Ritchie Boys World War II military intelligence interrogation team.

As the only person from his Jewish family to flee Nazi Germany, he came to the United States and later served in the US Army conducting frontline interrogations.

[3] After witnessing the start of anti-Semitic policies under the Nazis, Stern's parents hatched a plan to send him to the United States to stay with his Uncle Benno and Aunt Ethel.

He became active in his school community, joining the newspaper team and landing interviews with figures like Benny Goodman and Thomas Mann.

He was later drafted in 1943, beginning weeks of basic training and legally changing his name from Günther to Guy in case of capture by enemies.

There he studied enemy intelligence and different uniforms, memorized battle orders and aerial maps, and mostly learned how to conduct interrogations.

[2] The four most useful interrogation tactics he learned were the power of knowledge, bribery, common interests, and invoking fear, all to be done without violating the Geneva Conventions on Warfare.

After months of training, Stern and the other Ritchie Boys returned to Europe on D-Day, where he became a member of a six-man IPW (Interrogators of Prisoners of War) Team 41.

After several successful interrogations, Stern was promoted to head of his team and prepared various reports based on answers from prisoners for his commanders.

One of their most important interrogations included learning about the execution of two fellow Ritchie Boys of another team, leading to the capture and trial of their murderer.

[19] Stern was the director of the Harry and Wanda Zekelman International Institute of the Righteous at the Holocaust Memorial Center in Farmington Hills (near Detroit).
