Private scholar; art historian of the baroque and modern periods; methodological theorist. Badt was born to a prosperous Banking family in Berlin. His father, Leopold Badt (1858-1929) raised his children in a rarefied cultural atmosphere, giving them every opportunity to experience art. The younger Badt attended the Berlin-Charlottenburg Reformgymnasium, graduating in 1906. Between 1909-1914 he studied art history and philosophy at the universities of Berlin, Munich and finally at Freiburg (im Breisgau) under Wilhelm Vöge.
