Willibald Utz was born in Furth im Wald in Bavaria on 20 January 1893.

[2] In April 1943, Utz was appointed commander of the newly reconstituted 100th Jäger Division, which had been destroyed at the end of the Battle of Stalingrad.

Promoted to major general (generalmajor) on 1 July 1943, he held his command on the Eastern Front from March to December 1944.

After fighting on the Western Front in the Saar-Moselle Triangle, his new command, earlier in the war considered an elite unit, was well below strength and combat effectiveness.

The division finished the war in Württemberg where Utz surrendered it to the Western Allies.
