Born in 1904, Pamina Mahrenholz studied sculpture in Berlin, winning the Prix de Rome, which Nazi pressure prevented her from taking up. Mahrenholz immigrated to Britain in 1939, where she was initially imprisoned in Holloway Women's Prison, then interned on the Isle of Man from 1940 to 1942, like Collection founder Ruth Borchard. Following this, Mahrenholz took up work as a china restorer, eventually resuming her sculptural practice and taking up painting and drawing. Throughout her career, Mahrenholz held several exhibitions, including at the Camden Institute, Ben Uri Gallery, Camden Arts Centre and the Boundary Gallery, all in London. Mahrenholz's self-portrait was acquired by Ruth Borchard Collection in 2011.
Mahrenholz's oeuvre consists mostly of figurative work, both painted and sculpted. Her work explores themes of identity and migration.
