Debuting in Milan, Fontana settled in Paris in the mid-1930s, where he joined the Abstraction-Création group and created expressionist sculptures in ceramic and bronze. He later moved to Argentina, where he developed his highly influential Technical Manifesto of Spatialism, a modernist marvel, characteristic of postwar innovation and fueled by a forward-looking synthesis of art, technology, and science. With Spatialism, the artist sought to project color and form into spaces, most famously in his minimally ripped or slashed canvases, such as his extensive Spatial Concept Waiting series.
