Chuck Berry, the rock 'n' roll founder who defined its joy and rebellion in ``Johnny B. Goode'' and other classics, has died in St. Charles County, Missouri, west of St. Louis. 

St. Charles county police say they responded to a medical emergency Saturday afternoon and found Berry unresponsive. He could not be revived and was pronounced dead.
