I read this somewhere ... it seemed interesting, so I thought I'd share:
Some time after Salvador Dali’s death, his younger brother became famous
as (believe it or not) a surrealist painter. This younger brother had
great international success and the word genius was used to describe
him. His name was Dali and he did not change it. Yet today, the word
remembers only one Dali and few even know he had a brother. Why is this?
