Von Schreiber

Admiral Von Schreiber is a supporting antagonist of the 1959 musical The Sound of Music and its 1965 film adaptation. He is a German Navy Admiral who is in league with Hans Zeller and intends to bring Captain Georg von Trapp into the service of Nazi Germany.

Role
When Austria was annexed into Nazi Germany (several days after Captain Georg Von Trapp and Maria Rainer were married), Zeller was appointed as the new Gauleiter of Austria by Adolf Hitler As part of his job, Karl is assigned to help maintain Nazi order around Austria at all costs with the help from his right-hand Lieutenant Karl.

When Rolf Gruber delivers a message to Von Trapp, it details an offer for him to accept a commission in the Kriegsmarine (the Nazi Navy) at the German Naval base in Bremerhaven. To ensure of this, Zeller sent in Von Schriber to personally escort the Captain to Bremerhaven to accept the commission. However, the Captain is secretly unwilling to join the Nazis, so he stated that he's actually driving his family to the Salzburg Music Festival (since his children are among the contestants). Von Schriber allows this, but states that he will deliver the Captain to Bremerhaven after the festival is over.

However, the Von Trapp family escaped after finishing their performance, much to Von Schriber's shock. As such, Zeller orders all of his officers to track down the Von Trapp family, but their efforts proved to be futile as the family have escaped into the mountains.

It is unknown what happened to Von Schriber following the Von Trapp family's escape to Switzerland.

Trivia

 * A key difference between the movie and the play:
 * In the play, Von Schriber only appeared during the Von Trapps' attempted escape from their estate and plays the role of escorting them to the festival for good measures.
 * In the movie, Von Schriber doesn't appear, but is mentioned by Zeller, who takes on the Admiral's role of escorting the family to the Festival for good measure.
