Thaddeus Mosley, a self-taught Pittsburgh sculptor who gained international acclaim in his 90s, has died at 99. The artist, who transformed reclaimed wood into abstract works inspired by Brancusi, Noguchi, and African art, spent nearly 70 years creating in relative obscurity before his breakthrough at age 92.

Mosley's journey began in the 1950s when he was inspired by decorative teak birds at Kaufmann's department store in Pittsburgh. Working from his basement studio, he collected discarded trees from Pittsburgh parks and carved them into textured, biomorphic sculptures. His work, which often appeared precarious but was always stable, reflected influences from modernist masters and pre-modern African tribal sculpture.

His late-career recognition came in 2018 when he was included in the 57th edition of Carnegie International. This led to rapid opportunities: exhibitions at Karma gallery, displays at Rockefeller Center and City Hall Park, and the 2022 Isamu Noguchi Award. Despite racial and economic barriers that kept him in Pittsburgh rather than moving to New York, Mosley persisted, working daily in his studio while maintaining a postal service job to support his family.
