Jacqueline Stieger was born in 1936, and studied painting at Edinburgh College of Art from 1953-59. Between 1965-69 she worked and exhibited widely in Switzerland, carrying out special church commissions in wood, glass and lead.

She married Alfred Gruber, a sculptor and jeweller, and they moved to Yorkshire where they set up their own foundry in Welton, Humberside. Casting in gold, silver and bronze, Jacqueline uses the lost wax technique, her work ranging from large pieces of sculpture, to art medals and jewellery. She made a series of medals in bronze to celebrate important goldsmiths exhibitions, with the British Art Medal Society became a principle patron.

In 1985 she was awarded the Freedom of the Worshipful Company of Goldsmiths and the Freedom of the City of London, and in 1986 she became a Fellow of the Royal Society of Arts.

As a jeweller, sculptor and medallist, she has exhibited widely, her works ranging from public commissions, work for churches and universities and private commissions for individuals clients.

Many of her works are in public and private collections, including the Goldsmiths’ Hall Collection.
