Martin Schaffner (1478–1548),
was a German painter and medallist. He was born, lived and worked primarily in Ulm. His birth year is calculated based on a self-portrait medal he created in 1522 in which he describes himself as 44 years old. Schaffner initially apprenticed under Jörg Stocker. Records indicate he was a taxpaying householder in Ulm in 1499, suggesting that he had meanwhile become an independent master, free to develop along his own lines. He specialized in religious-themed works, often altar pieces. He died in Ulm in 1548.
