Sandra Samuel (born c. 1964) is an Indian nanny who saved the life of two-year-old Moshe Holtzberg during the November 2008 Mumbai terrorist attacks. Samuel saved Holtzberg when Nariman House was attacked by the terrorists. Both of Holtzberg's parents were killed in the attack. Samuel is still employed as a nanny for the boy, now in Israel.
Samuel had been living in the Mumbai Chabad House and working for Rabbi Gavriel Holtzberg and his wife, Rivka, since 2003. The Holtzbergs were the Israel-born directors of the house run by the global Orthodox Jewish Chabad movement. Samuel had been the nanny caring for the Holtzbergs' son Moshe since his birth. Samuel stated that she called them "my rabbi" and "my Rivki." When she started working there in 2003, it was expected to be a temporary job but she stated that she was "so captivated by their generous, courageous spirits" that she stayed on. When Moshe was born, she took the role of nanny.
In June 2008, her husband, John, a Keralite who worked as a mechanic, died suddenly in his sleep of an undiagnosed illness. She has two sons, Martin and Jackson, who were aged 18 and 25 at the time of the attack. She is a Christian. Samuel's family was originally from Goa but she lived most of her life in Mumbai.
On 26 November 2008, as the Mumbai attacks began, a group of attackers entered the Chabad house and began shooting at everyone inside. Samuel heard gunshots and locked herself in a laundry room as she heard Rivka screaming. Later, she heard Moshe calling out her name and crying. After emerging from the room and running upstairs, she found Gavriel and Rivka motionless and covered in blood with Moshe crying beside them, his pants drenched in blood. With the attackers still inside, Samuel said she grabbed Moshe and ran from the building. Later, when Indian commando teams stormed the house, it was confirmed that Gavriel and Rivka were among the 173 people killed in the attacks, and that Moshe was now an orphan.
