Alicja Piotrowska graduated from medical studies at the Faculty of Medicine of the University of Warsaw in January 1939. During the occupation, she worked in the surgical ward at the Baby Jesus Hospital in Warsaw.
In April 1943, a few days before the outbreak of the Warsaw Ghetto Uprising, Miriam Sokołowska escaped to the Aryan side, where, as a Pole, found work and accommodation with a family of farmers living near Warsaw.
After a few months, Miriam became ill with tetanus. The hostess took her in a serious condition to the Baby Jesus Hospital, where Miriam confessed being a Jew to a nurse. The nurse immediately informed doctor Alicja Piotrowska about this fact, and the doctor took care of the patient, placing her in a separate room. She took care of her throughout her illness and, when she recovered, provided her with false documents, money and cyanide in case of arrest by the Germans.
After the fall of the Warsaw Uprising, Miriam met doctor Piotrowska in Milanówek. Alicja Piotrowska took her to her house and hid her until the liberation. After the war, Miriam Sokołowska emigrated to Israel.
