At the age of ten, it was mandatory that I join the Deutsches Jungvolk (DJV), the junior branch of the Hitlerjugend or Hitler Youth.

I was selected by Reichsjugendführer Artur Axmann to be a member of a Hitlerjugend Helden (Hitler Youth Heroes) delegation to visit the Führer in Berlin on his birthday.

I met Adolf Hitler in the Reich Chancellery garden (also known as the Hinterhof or backyard) outside his bunker on his last birthday, April 20, 1945.

I was able to observe the final days of Hitler, Eva Braun, Martin Bormann, and Joseph Goebbels and his family.

From 1955 to 1957, Lehmann taught at the United States Armed Forces Institute, and also served as transportation coordinator at Tachikawa AFB in Japan.

In the cause of peace, Lehmann traveled to more than 150 countries, speaking out for non-violence, tolerance, and understanding with such other voices as Jawaharlal Nehru and Albert Schweitzer to all who would listen.
