Abraham Bernstein is the grandfather in the Bernstein household and good friends with Ruby Engels. When the Maxwell family needs shelter to escape the Visitors, Abraham offers them the shed in the back yard of the Bernstein house. Being a Holocaust survivor, he saw parallels between the Visitors persecution of the scientists and the Nazi persecution of the Jews.When a neighbour’s family, the Maxwells, need a place to hide, Abraham offered up the Bernstein pool house. Stanley, his son first disagreed with him and wasn’t going to allow it until Abraham gave him a heartfelt speech informing his son for the first time that during the Holocaust, Stanley's mother didn’t have a heart attack in the box car like he had been told, but had made it to the camp and died in the showers. Abraham offered that if only someone had given them a place to hide, she would still be alive. Stanley was convinced.
Walking around town, he found some teens vandalizing a "Visitors are our Friends" poster, when he intervened and taught them to spray a big red V over the poster, for victory, inspiring the symbol of the resistance everywhere.
Soon after, Abraham was shocked and disgusted when his grandson threatened to turn the Maxwells in unless Robin agreed to marry him. Realising what Daniel was going to do, Abraham camped out in the pool house and accepted that the aliens were going to arrest him.
Abraham never returned home and it is implied that he was killed on the mothership. (V: The Original Miniseries)
