Deborah Butterfield is an American sculptor, she was born in 1949 in San Diego. She and her husband, John Bock, a sculptor, live between their ranch in Montana and their studio in Hawaii. She received her master's degree from the University of California, Davis. Deborah is famous for her sculptures of horses. She uses metal and wood. At first, she used natural materials such as mud, clay and wood to make sculptures, then she also experimented with metal. From 1979 onwards, she used recycled materials such as steel and scrap metals in her works. Butterfield's way of using minimalistic materials - wood shavings, clay and steel chips - to evoke the figure of a horse - has greatly impressed critics. Deborah Yellin writes: The volume and detail of Butterfield's works show how masterful she is in working with metal. According to Yellin, Butterfield is completely in control of her composition and is a master in understanding the essence of the unique animals she creates. Butterfield's works inspire critics to write about their own feelings of encountering them.
