Theodor Casella (August 8, 1900 – November 9, 1923) was a bank clerk who participated in the attempted Nazi overthrow of the Bavarian Government. Casella was one of the sixteen Nazis to have been killed in the Beer Hall Putsch. He along with others are considered the first "martyrs" in the Nazi Regime and his death would become part of occult practices of the regime. Adolf Hitler dedicated his book Mein Kampf to him and the others who died.
