Herbert Ferber was an abstract expressionist sculptor associated with The Irascibles, a group of artists who protested the lack of abstract art in a Metropolitan Museum of Art exhibition in 1950. He is one of the American artists who rejected the then conventional idea that sculpture should be comprised of solid masses; instead, Ferber created open, airy forms that in his own words “pierced” space. Throughout the 1930s, Ferber worked primarily with carved wood and stone in a figurative style, but he stopped making wood sculptures in the mid-1940s. Inspired by Henry Moore, Ferber began experimenting with steel-reinforced concrete and abstract forms. He is credited with creating one of the earliest environmental sculptures in 1960. Ferber was also an accomplished painter; he applied abstract motifs to the relief-like bases of his sculptures.
