Their eldest son Christoffel Blum (bapt 21 Jan 1552) was named after the publisher Christoffel Froschauer (?1490–1564), who later published Hans Blum’s treatises on architecture.
Hans Blum is primarily known as the author of Quinque columnarum exacta descriptio atque delinaeatio cum symmetrica (1550), a book on the five orders of architecture.
