Thornton Dial was a pioneering American artist who came to prominence in the late 1980s. Dial's body of work exhibits formal variety through expressive, densely composed assemblages of found materials, often executed on a monumental scale. His range of subjects embraces a broad sweep of history, from human rights to natural disasters and current events. Dial's works are widely held in American museums; ten of Dial's works were acquired by the Metropolitan Museum of Art in 2014.
