Borngen and L. D. Schmadel at Tautenburg. French physicist Louis-Victor de Broglie (1892-1987), late in deciding on his career, chose for his doctoral thesis in 1924 a revolutionary theory of electron waves, exposing the duality between wave and corpuscle and founding the wave-theory of matter. He received the 1929 Nobel Prize in physics.
