Martha Nieuwenhuijs, born in Amsterdam (NL) in 1946, spent her early years in Paris and then moved to Turin (I) in 1966, where she attained a university degree in political sciences and where she currently lives and works.
In 1973 she began to experiment with Fiber Art creating wall hangings in mixed techniques and promoting Fiber Art in Italy where it was practically unknown.
In 1998 she founded the International Biennial of Fiber Art "Trame d'autore" in Chieri (Turin), where she was invited to exhibit her "white works" made during 1993-1998, in the solo exhibition Incontri Monografici d'artista (catalogue with critical essay by Piero Simondo).

The Chieri Civic collection of Fiber art, now endowed with more than 80 works of international artists , started after she donated her work The crowd to the city.

In the early nineties the artist created jewellery with the lost wax casting technique, the so called Con-Fusioni d'artista, a series of thirty small wearable sculptures realized during the years 1994-2004.
Between 2001-2004 she created Metamorphosis, a project inspired by major concerns of our time particularly by the transformations undergone by both the environment and human life in moments of crisis.
The large-sized mixed-techniques works were exhibited in collaboration with the sculptor and performer Rudi Punzo under the aegis of the town of Collegno (Turin) in 2004.
Her current research focuses on painting and making artist's books.
Her interest in shared art led her to realise with the painter Claudio Jaccarino two series of artists' books, Metamorfosi (2004) and Sguardi (2005), and the exhibition Incontri (2005) with the artist calligraphist Chen Li.

In 2003 and 2005 she participated in the International Art Simposium in Verbania (Italy), in 2005-2007 in Alea Jacta and Il legame misconosciuto, both organized by Adriano Accattino in Ivrea (Italy) and in 2006 and 2007 in the International European Artists Symposium in Essen (Germany).
Her works have been on show in Italy, France, the Netherlands, Germany, Austria, Hungary, Poland Spain, Switzerland.

She is member of European Artists e.v.
