Walther Meissner
1968
A portrait of Walther Meissner, who with Robert Ochsenfeld showed in 1933 that a superconductor does not merely fail to resist current but actively expels magnetic field from its interior - perfect diamagnetism. This is the result that made superconductivity a magnetic phenomenon, not just an electrical one.
