Helmuth Günther Guddat Hübener (8 January 1925 – 27 October 1942) was a German youth who was executed at age 17 by beheading for his opposition to the Nazi regime.

His friend and fellow resistance fighter Rudolf "Rudi" Wobbe later reported that of the 2,000 Latter-day Saints in the Hamburg area, only seven were pro-Nazi, but five of them happened to be in his and Hübener's St. Georg Branch (congregation), thus stirring controversy with the majority who were non- or anti-Nazis.

[5] Helmuth began listening to the BBC on his own, and he used what he heard to compose various anti-National Socialist texts and anti-war leaflets, of which he also made many copies.

[1] The leaflets were designed to bring to people's attention how skewed the official reports about World War II from Berlin were, as well as to point out Adolf Hitler's, Joseph Goebbels', and other leading Nazis' criminal behaviour.

In late 1941, his listening involved three friends: Karl-Heinz Schnibbe and Rudi Wobbe, both of whom were fellow Latter-day Saints, and later Gerhard Düwer.

While trying to translate the pamphlets into French and have them distributed among prisoners of war, he had been noticed by co-worker and Nazi Party member Heinrich Mohn, who denounced him.

It was highly unusual for the Nazis to try an underaged defendant, much less sentence him to death, but the court stated that Hübener had shown more than average intelligence for a boy his age.

Hübener's lawyers, his mother, and the Berlin Gestapo appealed for clemency in his case, hoping to have his sentence commuted to life imprisonment.

The Reich Youth Leadership (Reichsjugendführung) disagreed, however, and stated that the danger posed by Hübener's activities to the German people's war effort made the death penalty necessary.

This recommendation did not change after Kristallnacht, which occurred the year following Grant's visit, after which he evacuated all non-German Latter-day Saint missionaries.

The local Latter-day Saint branch president, Arthur Zander (1907-1989), was a supporter of the Nazi Party,[citation needed] and had affixed a notice to the meetinghouse entrance stating "Jews not welcome".

[12] The day of his execution, Hübener wrote in a letter to a fellow branch member, "I know that God lives and He will be the Just Judge in this matter… I look forward to seeing you in a better world!"

[13] In 1946, four years later and after the war, Hübener was posthumously reinstated into the LDS Church by the new mission president, Max Zimmer, saying the excommunication was not carried through with the proper procedures.

At the former Plötzensee Prison in Berlin, an exhibit about young Helmuth Hübener's resistance, trial, and execution was located in the former guillotine chamber that has since been changed to highlight other victims.

[16] In 1995, the first-hand account When Truth Was Treason was published, narrated by Karl-Heinz Schnibbe and written by Blair R. Holmes, a professional historian, and Alan F. Keele, a German-language specialist.

[17] Published in 1989, the book provides a personal account of his own trial before the Special People's court of Nazi Germany where he was sentenced to 10 years in prison for his participation in anti-Nazi resistance.
