Mary Levi lived in the Bulgarian capital Sofia with her husband Abraham and their daughters Nina and Erika.
In May 1943 a doctor friend, Pavel Gerdjikov, warned Mary and Abraham Levi that the deportation of the Jewish population was planned. The doctor offered to hide the Levis in his medical practice. Mary Levi moved in with her husband and two daughters. They hid in a locked room with a window and toilet. An additional emergency hiding place was set up behind a bookcase.
When the building was hit during an Allied air raid, Gerdjikov rented new accommodation for them in a village outside Sofia. Mary Levi and her family survived there, under non-Jewish identities.
Mary Levi emigrated to Israel with her family in 1948.
