Mainly known as Madame Eta, she was particularly known for flattering ready-to-wear clothing inspired by Ancient Greece and the Middle Ages.
Born in Budapest, Hentz studied at the Hungarian Royal State Academy of Industrial Arts.
[1] She worked in the ready-to-wear industry, creating clothes that were inventive, chic and refined, and flattering, especially for more mature women.
[2][3] She celebrated her 25th anniversary as a designer in July 1948, with an Autumn collection in shades of grey showing Victorian and Edwardian influences.
In 1957, as a "leader of the fashion industry" she helped found a costume library and reference collection at the college,[3] and was part of the college's Fashion Advisory Board in 1967 along with Mary Brooks Picken, Adele Simpson, Vera Maxwell, Jo Copeland, Pauline Trigère, Sally Victor, and Helen Lee.
