Grant M. DePorter is a restaurateur from Chicago, U.S., who came to prominence in 2004 after he paid US$113,824.16 for a baseball which had played a role in the Chicago Cubs defeat in the 2003 National League Championship Series, and had the ball destroyed in a nationally televised event. The event was an attempt to end the "Curse of the Billy Goat" – which has supposedly prevented the Cubs from winning the National League since 1945 and also helped raise a substantial amount of money for diabetes research.
