Hildegard Nörenberg (1904-1977) was a nurse and midwife from Berlin-Tegel, Berlin, Germany. She immigrated to Alabama in 1956, as her sister Maria, the wife of Operation Paperclip engineer Werner Kuers, had moved to Huntsville, Alabama in the early 1950s. From 1924 to 1932, Nörenberg frequently corresponded with Hans Albert Silberberg, her close friend and longtime love. Silberberg was a music student, composer, and pianist. He died in 1932, at the age of 25.
