Hanging on the wall of my museum is a large “Map of Physics” published by the Central Scientific Company in 1938. On it is a list of the Nobel Prizes in physics, starting with Roentgen in 1901 and ending with Fermi in 1938. I can recognize every name except the one for 1912: Nils Gustav Dalén. Perhaps you have had the same experience when looking through the updated list.
