Don Campbell, the author who convinced millions around the world that listening to the music of Wolfgang Amadeus Mozart makes you smarter, died Saturday at 65 in Colorado, his publicist told the Associated Press. He reportedly had pancreatic cancer.
Campbell wrote the bestselling 1997 book "The Mozart Effect," which argued that listening to the music of Mozart benefits mental and bodily functions, and raises the listener's cognitive levels. His book "The Mozart Effect for Children" persuaded many parents to play Mozart recordings to their children in the belief that the music would enhance brain development.
