Upon her retirement from the stage in 1948, Némethy was named a lifelong member of the Hungarian State Opera House. A 1936 recording of her Judith to Mihály Székely's Bluebeard was posthumously released on CD in 2015. Her performance of Ortrud in "Lohengrin" is also preserved on a 1948 recording with conductor Otto Klemperer.
