Jean Osborne, a Northern Irish painter known for her oils and watercolours, dies on July 9, 1965, at the age of 39, at Lisburn Hospital in Lisburn, County Antrim, Northern Ireland, due to a brain tumour.

Osborne (née Meikle) is born on February 21, 1926 in Larne, County Antrim, the daughter of William Meikle who is a fitter at Harland & Wolff. She displays artistic talent from a young age, recognized at 20 by painter Paul Nietsche, and earns a scholarship from the Ministry of Education to pursue further studies. She trains at the Camberwell School of Arts & Crafts in London and later completes her National Diploma in Art and Design at the Belfast School of Art.

Osborne’s early career includes exhibitions in Belfast, London, and prominent Canadian galleries after she emigrates to Canada with her husband, fellow artist Dennis H. Osborne, in 1953. She exhibits works such as The Harmonica Player, a portrait of poet Barbara Hunter, and other pieces across Canada, gaining recognition for her skill in landscapes, portraits, and abstract forms.

Declining health due to a brain tumour forces Osborne to return to Northern Ireland in 1959. She settles first in Portadown and later in Lisburn, where she continues to paint despite her illness. She participates in exhibitions, including those of the Royal Ulster Academy of Arts and local art societies, maintaining her influence on the Northern Irish art scene.

Osborne dies at the age of 39 on July 9, 1965, in Lisburn Hospital due to complications from a brain tumour, which had been a long-standing health struggle. She leaves behind her husband, Dennis, and their daughter, Moya. Posthumously, her work is celebrated in memorial exhibitions, including those organized by the Arts Council of Northern Ireland and the Ulster Society of Women Artists, and several of her paintings, like Roots and Grief, are preserved in the Ulster Museum and Armagh County Museum.

Osborne is remembered as a gifted painter whose contributions to mid-20th-century art in both the United Kingdom and Canada reflect emotional depth, modernist abstraction, and a commitment to capturing natural forms, despite her life and career being cut tragically short.
