Sylvia Salvesen (25 January 1890 – 19 June 1973) was a member of the high society in Norway, and a resistance pioneer during World War II.

She was then transferred with the ship SS Monte Rosa to Aarhus, and further by train transport via Hamburg to the Ravensbrück concentration camp in Germany.

[11] The families Hjort and Seip had received a letter from professor Harald Salvesen at Rikshospitalet, asking whether they could get his wife Sylvia's signature on a document and deliver a packet to her.

Later, Wanda managed to achieve a Sprecherlaubnis from a higher SS officer in Berlin, and with this document she was presented to her "aunt", Ravensbrück prisoner 20,837 Sylvia Salvesen.

[12][13] Salvesen was later able to send a complete list of the Norwegian female prisoners in Ravensbrück, brought by a German nurse to the people in Gross Kreutz.

These incidents included the practice of induced abortion of pregnancy, treatment of newborn babies in a way that resulted in death of most of them, experimental surgery on patients, "selection for transports" to the gas chambers, and sterilizing of gypsies.
