(Berlin, Germany: 8th March 1910 - Riga: 8th September 1942)
Günther Dammann was a German author and amateur magician who wrote on the history of magic. He started magic in 1924 and used the stage name Robertini. He learned magic under Ernest Thorn. After studying business and philosophy he worked in the bank of his father. Kalanag (Helmut Schreiber) warned Dammann that his 1933 book on Jewish magicians might inspire Nazi wrath. In 1942 he was deported and killed near Riga, Latvia, by the Nazis.
The three books he published are Juden in der Zauberkunst (1933), Meister der Zauberkunst (1936), and Zauberkunst und Zauberkünstler (1937).
