Eileen Stellar Kramer, a woman considered a "trailblazer" and national treasure, has died on Friday aged 110. 

The artist, dancer, choreographer and writer celebrated her birthday last week and was the oldest woman in New South Wales, according to her loved ones.

Born in Sydney on November 8, 1914, Ms Kramer spent the majority of her life performing around Australia and the world.

Ms Kramer became involved in the Bodenwieser Ballet in her late 20s, an institution considered to be the country's first modern dance company.

"I was about 24, I was taken to see a performance of the Bodenwieser Ballet that had recently come from central Europe and I fell in love with it straight away," she said in 2023.

Within three years, she became a member of the company. 

Over her career, she also worked and lived in India, Paris, London and New York. 

Ms Kramer returned to Sydney aged 99 following a 20-year period away from dancing to care for her ailing husband.

Shortly after returning to NSW, she was named ambassador for the Arts Health Institute, with the national advocacy body financially supporting her to continue her work. 

The same group also viewed Ms Kramer as a national treasure.

In 2017, at 103, Ms Kramer choreographed and performed in the production A Buddha's Wife as the 17-year-old princess.

In a statement, Ms Kramer's legal enduring guardians described her as a "trailblazer" and "true creative spirit" and said she died "peacefully".

"She is the last dancer of the Bodenwieser era, she was the longest living woman in NSW and most likely the longest living dancer internationally."
