An early attack on his wave theory of light was so scathing that English physicists buried it for nearly two decades until it was rediscovered in France. But slowly, after his death, great scientists began to recognize his genius. Today, in an age of professional specialization unimaginable in 1800, polymathy still disturbs us.
