Artist and teacher, born at Mumbles, near Swansea, who studied painting, sculpture and stained glass at the College of Art there, remaining as a tutor, 1957–73, when she returned to full-time painting. Her teachers included Alfred Janes, William Price and George Fairley. Ganz became preoccupied by the landscape of south Wales, concentrating on industrial, especially mining, areas. In 1985 Ganz took a house and studio at Six Bells, Abertillery, for nearly a year depicting the lives of the miners at its colliery, underground and on the surface, with their families at choir practice, in the snooker halls and at chapel. The work was widely exhibited, notably at the mining show at Glynn Vivian Art Gallery, Swansea, in 1986. In 1990 Ganz was commissioned by British Coal Opencast to study three sites in south Wales and she later worked at Tower Colliery.
