Käthe von Nagy

During the Second World War, Nagy virtually retired from the acting industry, appearing in only one movie, Mahlia la métisse. Because of her notability due to her famous and hugely popular postcards, she was, in 1940, reportedly approached by Reichsführer-SS, Heinrich Himmler, who asked her to be the face and body for sex dolls provided to German soldiers as a way to combat syphilis at the front, but she refused. This story has come to be considered a hoax, due to the lack of reliable sources backing it up.

Nagy's first marriage was to film director Constantin J. David, in 1927, the same year they met. Her second marriage was to Jacques Fattini; little is known about their relationship and marriage. She died of cancer in 1973, in Ojai, California, aged 69.

In 1926, Nagy moved to Berlin to pursue a career in the film industry, but, as she was then unknown, she took a position as correspondent for the Hungarian newspaper Pesti Hírlap to earn a living. After numerous futile applications in the city, Hungarian film director Alexander Korda got her a role as an actress in the 1927 comedy film Männer vor der Ehe, opposite her future husband, Constantin J. David. Soon after, in 1928, she starred in the successful Wien, die Stadt meiner Träume ("Vienna, City of My Dreams"), which made her known as the "up-and-coming young actress of the European cinema". She later appeared in many leading roles and became famous for her countless postcards which also benefitted her modeling career. In 1931, she starred in Le Capitaine Craddock, which made her notable in France where she would later make half her movies. From 1937 onwards, she was mainly in French-speaking roles, but also appeared in Italian and Austrian film productions. Her last film was the German film The Forester's Daughter, in 1952, alongside Johanna Matz.

Ekaterina Nagy von Cziser, better known by her stage name Käthe von Nagy (4 April 1904 – 20 December 1973), was a Hungarian actress, model, dancer, and singer who worked in the German and French cinema.
