In the 1939 Bad Kreuznach book of inhabitants (presumably presenting 1938 figures), five Jewish families are still listed: Karl Mayer, Rudolf Mayer, Fritz Natt, August Weiss and Moritz Weiss. On Kristallnacht (9–10 November 1938), the synagogue was utterly demolished by Nazi brigands from within Langenlonsheim and without.

The Jewish men were taken away to Dachau concentration camp. After the first deportation on 10 April 1942, Langenlonsheim's last two Jewish inhabitants, August Weiss and his wife Isabella Weiss "née" Furchheimer, were deported on 25 April 1942.
