Mirjam Verhoeff studied in Holland, at the Larense Vrije Academie and at the Slade School of Art in London. She studied further in Greece and Perugia (Italy). In 1970 she went to Vienna to visit the Spanish Riding School. The former director of the school, the late Colonel Hans Handler, offered her full facilities to work there. The result was an exhibition at the Albertina Museum of Vienna in September 1972, which marked the four hundred years anniversary of the foundation of the school.
Having exhibited at the Dublin Horse Show (1972) and at Pottergate Galleries in Norwich (1974), she held her first one-man show at Fortescue Swann Galleries, London in 1976 and continued to exhibit regularly at the Tryon Gallery.
She specialises in monochrome drawings of animals, often on a large scale and her bold use of mediuim is particularly accomplished and distinctive. Her work is in many collections throughout the world, including that of our own Royal Family.
