He was the elder brother, by about three years, of Hans Holbein the Younger, but he appears to have died in his mid-twenties, leaving behind only a small body of work.
Like his younger brother, he was born in Augsburg (which today is in Bavaria, but then was a free imperial city), a center of art, culture, and trade at that time.
