Winifred Coombe Tennant was the Evan Walters' patron
She was a suffragette, a supporter of Welsh Prime Minister Lloyd George, a psychic medium and for a decade wore traditional Welsh costume every day.
Now Winifred Coombe Tennant is being remembered as one of the significant art patrons of the last century.
A new exhibition in Cardiff delves into the life of the woman who befriended Welsh artists and collected their work.
The museum's curator Beth McIntyre described Coombe Tennant as a "fascinating woman".
"Last year we showcased the exhibition of international art collected by sisters Gwendoline and Margaret Davies," explained Beth McIntyre.
"This exhibition A Life Through Art will focus on Winifred Coombe Tennant's contribution."

Though not on the same scale as the famous collection of impressionist works collected by the Davies sisters from mid Wales, Winifred Coombe Tennant's work includes well known Welsh painters like Evan Walters, Sir Kyffin Williams, and Gwen John.
A person of moderate wealth who had married into a Neath family, she assisted the artists with personal support and was commended for her work in the development of young Welsh painters.
The exhibition, curated by art historian Peter Lord, brings together some 80 paintings.
Some of these Coombe Tennant bought for the Glynn Vivian Gallery, for which she was the official London buyer, and others she bought for herself.
The exhibition, organised by the National Library of Wales, also includes the patron's diaries and letters accompany which give an insight into her relationships with artists working in Wales.
"Due to her love of Kyffin Williams' work, the museum will display a large variety of his paintings.
"She was the first and most important patron of Evan Walters as she owned 49 of his works.
Coombe Tennant was a great admirer of Sir Kyffin Williams
"When she was young she knew Gwen John and meeting Augustus John after World War II was one of the highlights in her life."
But Ms McIntyre said the patron's life outside the world of art was equally consuming.
"She was a suffragette, she met Emily Pankhurst, she was a peace campaigner, she knew Lloyd George, she even stood for parliament."
Through her son, who was killed in World War I, Coombe Tennant also go involved with the National Eisteddfod for which she was a member of the gorsedd becoming the robes mistress.
"She was a great believer in natural dyes and promoting traditional Welsh clothes," explained Ms McIntrye.
"From 1898 for 10 years she wore the Welsh national costume every day."
Alongside her public life, she also worked in secret as a psychic medium.
"She had two children who died and she really believed that she could contact them and that there was something beyond bodily death."
This interest also impacted on her understanding of art, said Ms McIntyre.
"She liked to think that artists were geniuses - and that their work transcended pure images."
Winifred Coombe Tennant: A life through art will be housed at National Museum from 26 July till 9 November, 2008.
