Otto Holtenwasser is the Murphys' elderly German-Jewish neighbor. It is rumored by the neighborhood children, that he is a Nazi war criminal, when in reality, he is a Holocaust survivor. Despite this, he remains jovial and chipper and friendly to all his neighbors, though he will occasionally, bring up a sad memory from the holocaust. He is voiced by Trevor Devall.


Mr. Holtenwasser was born in Germany. Sometime prior to or during 20's , he was incarcerated in a concentration camp, during the holocaust, where many horrible things happened to him. Since the end of the holocaust, he has since moved to America, where he currently lives in the same neighborhood as The Murphy Family.

Most likely due to words getting twisted about his past, a playground rumor has the kids believing he is a Nazi and therefore are scared of him. Despite this, In "The Bleedin' in Sweden," Bill's magnet gets stuck to the numbers on Holtenwasser's house. When he reaches out to try and take it down for him, we can see the serial number tattooed on his arm. Bill thinks it is the number of people he's killed.

In "The Trough" he gives Kevin a ride home. He recounts to him how he's watched Kevin grow up throughout the years, seeing him playing around the neighborhood. He also mentions that he and his wife were the first homeowners in the subdivision. During this, Kevin notices a Star of David hanging from his rearview mirror but mistakes it for a pentagram. For this reason, Kevin (and later Bill) believes he is a Satan worshipper, even despite Frank's more accurate description of him as "a sad old man whose family was butchered in the war."

In "O Holy Moly Night," Holtenwasser is the one who finds the Murphys' dog, Major, after he ran away from the fireworks. He is also one of the guests at their Christmas party.

In "The Liar's Club," Holtenwasser joins Kevin and Frank and the rest of the neighborhood in the Murphy's basement, remarking he shared a basement with fourteen others in his lifetime. Vic likens this to a life of partying before Holtenwasser reflects it was, really, a very quiet life, "most of the time."

In "Punch Drunk", he and Ginny hook up after getting drunk during the block party. He is very regretful about it but has a hard time breaking it off with her.

MORE ABOUT THE 2nd PARAGRAPH: Mr. Holtenwasser, as mentioned in the first episode, has a number permanently placed on his arm, meaning he was in the holocaust, his number was "721437" he is an escaped Jew. Bill, thought the number was a scoreboard for how many people he has killed, Mr. Holtenwasser has never killed anyone.


Otto Holtenwasser is a friendly elderly man, who is always generous to his neighbors and especially kind to children. Although 99% of the time, Otto managed to keep a delightful and carefree demeanor, he will occasionally have a sudden change in mood, and abruptly bring up a brief, but detailed event, of what happened to him, during the holocaust, often killing the cheery vibe, that surrounds him.
