Isabel May Tweddle

Isabel May (Diana) Tweddle (1875–1945), was an Australian painter. She was a member of the Melbourne Society of Women Painters and Sculptors and the Twenty Melbourne Painters Society Inc.

Tweddle was born Isabel May Hunter on 26 November 1875 in New South Wales. From 1894 through 1897 she studied at the National Gallery School in Melbourne. There she met fellow artist Ada May Plante.

After her studies she began exhibiting at the Victorian Artists Society. In 1904 she married Joseph Thornton Tweddle, an Australian businessman and philanthropist. The couple traveled throughout Europe, and lived in London, England in 1921. Tweddle visited Scandinavia and the Pacific (the Solomon Islands, New Guinea, and Japan). Her paintings from those trips were exhibited in London.

Tweddle had an interest in Post-Impressionist art, mainly though the work of Arnold Shore and William Frater. She is thought to have influenced Sybil Craig, Peggie Crombie and Jessie Mackintosh.

She was a member of many artistic groups in Melbourne; the Contemporary Art Group, the Contemporary Art Society, the Melbourne Society of Women Painters and Sculptors, and the Women's Art Club.

Her paintings are in the collections of the Shepparton Art Museum, the National Gallery of Victoria, and the Art Gallery of New South Wales.

She died on 9 July 1945 in Melbourne.

Tweddle Place in the Canberra suburb of Chisholm is named in her honour.
