Erzsébet Rusznyak was born in Budapest on 26 December 1902, the daughter of Pál Ranschburg, a well-known neurologist, psychologist and pioneer of experimental educational methods in Hungary.
She was married to Endre Rusznyák who was an engineer.
She took refuge in Katalin with her two children, a daughter born in 1931 and a son, Andreas, born in 1936. She attended Dialogue N° 85 on 3 November 1944. She left the war factory after the Arrow Crosses attempted raid on 5 November 1944 (on this subject, read the testimony of Andreas Rusznyak). She and her family escaped deportation.
After the war and until 1957, she worked as a graphic designer with Gitta Mallasz, Agnes Péter and Adrienne Frankovszky in the latter's workshop which Gitta had taken over in 1945.

According to Eva Dános (letter of 26-11-1994 to PanosVyras) and Agnes Péter, she too received messages after the war.
