בבית זה התגורר, וכאן נרצח, ד"ר ישראל רודולף (רז’ה) קסטנר, מגדולי פעילי ההצלה בשואה. ישראל קסטנר היה איש ציבור ציוני אשר פעל עם חברי ועד ההצלה הציוני בבודפשט להצלת יהודים רבים: ברכבת ההצלה, במחנה שטרסהוף, בסיוע למחתרת תנועות הנוער, בהברחה, בהסתרה ובזיוף תעודות, וכן בהצלת אלפים רבים משורדי המחנות.
הוא עלה ארצה עם אשתו ובתו ב-1947. המשפט שנערך נגד מוציא דיבתו עורר הדים רבים.
ישראל קסטנר נורה במקום זה בידי מתנקשים יהודים והלך לעולמו ב-15.3.1957 זמן קצר לאחר מכן טוהר שמו בבית המשפט העליון.
מוקירי זכרו ופועלו, ניצולים וצאצאיהם, נאספים כאן שנה בשנה ביום הזיכרון לשואה ולגבורה לספר ולזכור את האיש וחבריו, ולהוקירם על התושיה ואומץ הלב שגילו במאבקם להציל חיים.

Israel (Rezső) Kasztner (1906-1957), was a member of the Budapest Aid and Rescue Committee and worked to save Jews, including the Kasztner Train in which 1,600 Jews were saved in exchange for paying a ransom to the Nazi authorities.
On the other hand, some claimed that Kastner collaborated with the Nazis. In 1952, Malchiel Greenwald published an article accusing Kastner of collaborating with the Nazis. In the libel trial held against Greenwald, he was acquitted of most of the charges against him (he was fined one Israeli pound).
Later, the Supreme Court ruled that Kastner did not collaborate with the Nazis, but noted that he had saved a Nazi criminal from the death penalty while telling a lie.
On March 3, 1957, Kastner was shot in the doorway of his house by three young men. Kastner died of his wounds on 15.3

There is no doubt that the sign, which was probably placed by his family, presents one side of the story.

Translation of the text on the sign:
In this house lived, and here was murdered, Dr. Israel Rudolf (Rezső) Kasztner, one of the greatest rescue activists in the Holocaust. Israel Kasztner was a Zionist public figure who worked with members of the Zionist Rescue Committee in Budapest to save many Jews: on the rescue train, in the Strasshof camp, in assisting the youth underground, in smuggling, in hiding and forging documents, and in saving many thousands of survivors of the camps.
He immigrated to Israel with his wife and daughter in 1947. The trial held against his slanderer caused many repercussions.
Israel Kasztner was shot here by Jewish assassins and died on March 15, 1957. Shortly thereafter, his name was cleared by the Supreme Court.
Those who cherish his memory and work, survivors and their descendants, gather here every year on Holocaust Remembrance and Heroism Day to tell and remember the man and his friends, and to honor them for the resourcefulness and courage they showed. In their fight to save lives.
