Where 1901 fits
Why 1901 is special
Nobel's will directed his fortune to prizes for those who conferred the greatest benefit on humankind, and his family contested it for years. He had made that fortune from dynamite, and a premature obituary condemning him as a merchant of death is commonly credited with prompting the bequest.
