Born in Cologne, Band was the son of the architect Heinrich Band (1855–1919), a long-time associate of the building councillor Hermann Otto Pflaume, whose office he also headed for a time. He was also related to the painter Michael Welter (1808–1892), who, among other things, painted the Cologne parish church Basilica of St. Cunibert, Cologne after the tower was rebuilt in the 19th century, and with Heinrich Band, the inventor of the bandoneon, a brother of his grandfather.
