Thaddeus Mosley, a self-taught artist who became an internationally known sculptor and a beloved Pittsburgh public figure, died on Friday, March 6, at the age of 99. For more than 70 years, Mosley carved figures using mallets and chisels out of salvaged wood from Pennsylvania forests before finding acclaim in his ninth decade with shows at the Musée National Eugène Delacroix in Paris, Bergen Kunsthall in Norway, the Baltimore Museum of Art, the Nasher Sculpture Center in Dallas, and elsewhere. Mosley frequently characterized his method as “sculptural improvisation.” Inspired by Constantin Brancusi, African tribal art, and Isamu Noguchi, for whom he had a particular affinity, as well as classical jazz, he approached his work by letting the forms of his raw materials speak to him. Instead of making variations on a theme or imposing a shape onto logs of wood, he used a chisel and gauge to respond to the natural gradations of its surface.
