In 1888, Alfred Nobel’s brother Ludvig passed away and a French newspaper mistaken Ludvig for Alfred and it ran a long obituary about Alfred. The copy said - "The merchant of death is dead" and it went on to say, "Dr. Alfred Nobel, who became rich by finding ways to kill more people faster than ever before, died yesterday.” This horrified Alfred and made him realize that he didn’t want to be remembered that way.
Thanks to that erroneous article, Nobel was given another chance at life and to promote something good even more than 100 years after his death.
