Alberto Burri (1915 - 1995)
Burri earned a medical degree in 1940 and was a military physician during World War II. After his unit was captured he was interned in a prisoner-of-war camp in Hereford, Texas in 1944, where he began to paint.
Burri soon turned to abstraction and unorthodox materials, making collages with pumice, tar, and burlap.
In the mid-1950s, Burri began producing charred wood and burlap works, then welded iron sheets. In the early 1960s he was burning plastic, and in the early 1970s started his "cracked" paintings, or cretti. He created a series of works in the industrial material, Cellotex, from 1979 through the 1990s.
In the 1980s, Burri created a land art project on the town of Gibellina in Sicily. The town was abandoned following an earthquake in 1968. Burri covered most of the old town, with white concrete. He called this the Grande Cretto.
